area circle = πr² or π(d/2)² but how to find the diameter?
The only angles I can see to calculate is in the small right triangle
The smaller angle on the right is ...
sin Ф = opp/hyp = 6/10 Ф = 36.87°
This angle is the same as the small angle on the LARGE right triangle
So now I want to calculate the side (diameter) opposite the smaller angle
sin Ф = opp/hyp = diameter/300 = sin 36.87°
diameter = 300 sin 36.87°
= 300 (6/10)
= 180 ft
area circle = πr² or π(d/2)²
area circle = π(180/2)²
area circle = 25446 ft² which is close to answer A 25434 ft²
There is actual no need to find the sin Ф wasted step
just use 6/10 small triangle is similar to diameter/300 the large triangle
opp / hyp small 6/10 = diameter/300 diameter = 180
area circle = π(180/2)² = 25446

The volume of a sphere is 62,208π cubic centimeters. Find the radius
Answers
Answer:
The radius of the sphere is 36 centimeters.
Step-by-step explanation:
Given that the volume of a sphere is 62,208π cubic centimeters, to find the radius the following calculation must be performed, knowing that the formula to obtain the volume of a sphere is V = 4/3 π x radius³:
62,208 x 3.14 = 4/3 x 3.14 x X³
195,333.12 = 4/3 x 3.14 x X³
195,333.12 = 4.18666 x X³
195,333.12 / 4.18666 = X³
46.656 = X³
³√ 46,656 = X
36 = X
Therefore, the radius of the sphere is 36 centimeters.
The time required to drive a fixed distance varies inversely as the speed. It takes 40 hr at a speed of 10 km/h to drive a fixed distance. How long will it take to drive the same distance at a speed of 8 km/h?
Answers
Answer:
50 hours
Step-by-step explanation:
Given data
Time=40hr
Speed=10km/hr
Let us find the fixed distance first
Speed= distance/Time
10= distance/40
distance= 10*40
distance= 400miles
Now our speed= 8km/h
hence the time is
8= 400/time
time= 400/8
time=50 hours
Hence the time is 50 hours

T, U, and V are
collinear. Suppose
U is between T and
V and that the
following is true:
TU = 7x - 4,
UV = 6x + 10, and
TV = 45.
Find TU.
Answers
The value of TU is 17.
Here,
T, U, and V are collinear.
U is between T and V
TU = 7x - 4,
UV = 6x + 10, and
TV = 45.
We have to find TU.
What are collinear points?
Three or more points are said to be collinear if they are lie on a single straight line.
Now,
T, U, and V are collinear.
U is between T and V
TU = 7x - 4,
UV = 6x + 10, and
TV = 45.
Clearly, TU + UV = TV
After putting the given values we get;
TU + UV = TV
(7x - 4) + (6x + 10) = 45
13x + 6 = 45
13x = 45 - 6
13x = 39
x = 3
Hence, TU = 7x - 4 = 7 * 3 - 4 = 21 - 4 = 17
So, The value of TU is 17.

Answer:
2/5 < 7/10
The least common denominator is 10 so if you do 5*2 = 10 and 2*2 = 4 then compare it to 7/10, it would be less than because 4/10 is not greater than 7/10.

How many groups of ¾ are there in 5
Answers
Answer:
6 2/3
Step-by-step explanation:
We can divide 5 by 3/4 to get the answer. 5 divided by 3/4 is the same thing as 5 times 4/3 which is 20/3 and 20/3= 6 2/3.
Hope this helps :)
It is found that the number of groups of ¾ there in 5 would be; 20/3.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division, is interpreted as equally dividing the number that is being divided into total x parts; where x is the number of parts the given number is divided.
We need to find the number of groups of ¾ there in 5.
Thus, We can divide 5 by 3/4 ;
5 divided by 3/4 is the same thing as 5 times 4/3 which will be;
5 / ¾ = 5 x 4/3
20/3
Also, 20/3 = 6 2/3.
So we can conclude that the number of groups of ¾ there in 5 would be; 20/3.

Step-by-step explanation:
the equation for point-slope form of the line is given as y-y1=m(x-x1) where (x1,y1) is a given point, and m is the slope
we are given the point (10,-1) that passes through the line and a slope of -3
so we can substitute what we know into our equation
y--1=-3(x-10)
