someone help I don't know what the diameter or radius is
52.38 inch² & 261.90 inch²
Step-by-step explanation:Here we need to find the area of the sector . So according to formula we know the area of sector as ,
[tex]\boxed {\sf Area_{(sector)}= \dfrac{\theta}{360}\times \pi r^2 }[/tex]
Here we can see that the central angle subtended by the arc is 60° and the radius of the circle is 10 inches . So the required area would be ,
=> Area = ∅/ 360° × π r²
=> Area = 60°/360° × 22/7 × (10in.)²
=> Area = 1/6 * 22/7 * 100 in²
=> Area = 52 .380 in²
★ Hence the area of the red sector is 52.38 inch²._________________________________
Now let's find out the area of blue sector .The angle subtended by the arc will be (360-60)°=300° .
=> Area = 300/360 × 22/7 × 100 in²
=> Area = 261. 90 in²
★ Hence the area of blue sector is 261.90 inch².[tex]\boxed{\red{\sf Area _{(red \ sector )} = 52.38 in^2 }}[/tex]
[tex]\boxed{\blue{\sf Area _{(blue \ sector )} = 261.90 in^2 }}[/tex]

The short sides measure 16 feet. What is the length of the longer sides of the pool
Answer:
40 for both of the long sides.
Step-by-step explanation:
Hope this helps! <3
Answer: Each long side is 20
Step-by-step explanation: If the short side were 16 then you would subtract 32 from 72. This would give you 40 you would divide this by two because you have two sides. So each long side is 20.

Latrell wants to fill his water bottle between classes, but the water fountain next to his classroom is frustratingly slow. It takes Latrell 5 seconds to get each ounce of water in his bottle. There is a proportional relationship between the amount of water (in ounces) Latrell puts in his water bottle, x, and how long in seconds) it takes to get that amount, y. Graph this relationship. Select two points to draw a line.
what is the slope of the line? _____
Answer:
Step-by-step explanation:
Slope = rise/ run, or y∨2 - y∨1/ x∨2 - x∨1
5-10/ 1-2 =
-5/-1 = 5
The slope of the line drawn from the given data is 5.
What is the slope?A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).
Given this, Latrell fills his bottle with one ounce of water in five seconds. The amount of water Latrell puts in his water bottle (in ounces), x, and the time (in seconds) it takes to get that amount, y, are proportionate. This connection can be graphed. Since, the line will pass from the origin(0, 0).
Since given y is the directly proportional equation of the line will be;
y = mx
where m is the slope of the line
Also given, filling the bottle at every ounce requires 5 seconds of time. hence, the line will go from (1, 5)
Thus, the value of the m will be;
5 = m *1
m =5
Therefore, the slope of the line is 5.

AC =using the Distance Formula
A. 10
B. 5
C. 15
Answer:
√41
Step-by-step explanation:
Here we want to find the value of AC
A = (-4,0)
C = (1,4)
The distance formula is;
D = √(y2-y1)^2 + (x2-x1)^2
D = √(4-0)^2 + (1-(-4)^2
D = √4^2 + 5^2
D = √(16+25)
D = √41

A rhombus has 10-in.Sides, two of which meet to form the indicated angle. Find the area of the rhombus.(Hint: Use a special right triangle to find height.) The angle is 30 degrees.
Answer:
50 in²
Step-by-step explanation:
Given that the side of the rhombus is 10 in, and it has an angle of 30°
The formula for the angle in a rhombus is given as
Sin Φ = height / side
Sin 30 = height / 10
height = 10 * sin 30
height = 10 * 0.5
height = 5 inches
One of the formulas for calculating the area of a rhombus is given as
Area = height * side, and thus, we have
Area = 5 * 10
Area = 50 square inches.
Therefore, the area of the rhombus is calculated to be 50 in²
