If you draw more of those triangles, there will be 6 that can fit, so find area of 1 triangle and multiply it by 6. Write that number down and then do Pi r squared to find the area of the circle, then do circle area minus triangles area when you get that, divide it by 6. That is the area of the white region so then do Pi R squared again and then subtract the white area from that

A circular swimming pool has a radius of 28 ft. There is a path all the way around the pool that is 4 ft wide. A fence is going

AleksAgata [21]

Answer:

200.96 feet

Step-by-step explanation:

We have a pool with a radius of 28 feet.

They also tell us that there is a path around the pool and its width is 4 feet.

Thus:

The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.

= (28 + 4) feet

= 32 feet

To find the length of the fence, we need to find the circumference of the outside of the pool path. The radius is then equal to 32 feet.

The circumference of the outer edge of the pool path would be equal to the perimeter.

p = 2 * pi * r

replacing

p = 2 * 3.14 * 32

p = 200.96 feet

therefore 200.96 feet are needed

The volume of a cylinder (shape of the soup can) is worked out by...
pi x radius^2 x h so...
pi x 1.625 (half diameter) ^2 x 4.5 = 37.33096 in^3 so it is closest to 37 cubic inches.
Hope this helps :)

just olya [345]

Answer:(-22)

Step-by-step explanation:

What is the value of h (-2) when h (3) = 32 +1?

hx3=33

33 divided by 3

which means h=11

that makes 11(-2)

=(-22)
