Find the area of a circle whose circumference is the same as the perimeter of a square of side 22 cm. (Take π = 22/7)

Answers

Answer 1

Answer:

Perimeter of a square=circumference of circle

4×22=2πr

44=πr

r=14

Area of circle=πr2

22/7×14×14

28×22

616

Answer 2

Answer:

176cm²

Step-by-step explanation:

Side of square = 22cm

Perimeter of square = 88cm

Circumference of circle = perimeter of square

2π r = 88cm

2 x 22/7 x r = 88cm

44/7 x r = 88cm

r = 88 x 7/44

r = 14cm

Area of circle = π x r x r

= 22/7 x 14 x 14

= 44 x 4

= 176 cm²

I believe the answer is 60.

First, I found the sides for each of the boxes, and pictured folding the box net into a 3D shape. Next, I found out that the top of the box was the box labeled with the 10 inches. Last, I found out that the side length of that box was 6, then I multiplied to get 60.

Im sorry if this is wrong, I do not know what the surface area is.

But I really hope it helps! TYSM! ;)

The graph shows information about the lion population at a safari park.

Lions were introduced in the park in 2010. In 2012, the park has a population of 32 lions. A year later, in 2013, the park has 128 lions. Write an exponential function that models this situation. Let xrepresent the number of years since 2010 and let f(x)represent the number of lions.

Tanya is training a turtle for a turtle race. For every 1/2 of an hour that the turtle is crawling, he can travel 2/23 of a mile. At what rate is the turtle crawling in miles per hour?

Answers

Answer:

To determine at what unit rate the turtle is crawling, divide 3/20 mile by 1/6 hour.

Therefore, the unit rate is 9/10 of a mile per hour

Step-by-step explanation:

The rate of turtle crawling is 4/23 miles per hour.

Given that, the time taken by turtle to crawl = 1/2 hour and number miles crawled by turtle = 2/23 mile

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Now, Speed = Distance/Time

= 2/23 ÷ 1/2

= 2/23 × 2/1

= 4/23 miles per hour

Hence, the rate of turtle crawling is 4/23 miles per hour.

Sean determines that the triangle shown in the diagram has angle measures of 40°, 40°, and 100°. Is Sean correct?

Answers

The bottom left angle is 180 -80=(100)

So the remaining 2 angles are equal 80
As all angles in a triangle are equal to 180

X+5 + x - 5 =80
Simplify
2x=80
X=40

Soo one of the angles are 40-5 which is (35)
And the other is 40+5 which is (45)
So sean is not correct
~sorry sean teehee

Answer:

Step-by-step explanation:

The two angles add to 80 degrees. Two remote angles always equal the exterior angle not connected to them.

That means that

x + 5 + x - 5 = 80

2x = 80

x = 40

The base angle  is

40 + 40 + y = 180

80 + y = 180

y = 100

Note

You could do this much quicker by noticing that

80 + y = 189

y = 100

No he is not right

The given 2 angles are x + 5 which is 45 and x - 5 which is 35

All he got correct was the fact that the third angle is 100 degrees.
