Answer: In didn’t now the answer but here.

Step-by-step explanation:

In general, an arc is any smooth curve joining two points. The length of an arc is known as its arc length. In a graph, a graph arc is an ordered pair of adjacent vertices. In particular, an arc is any portion (other than the entire curve) of the circumference of a circle.

A sphere has a surface area of 36π ft2. Find the volume of the sphere.
Stella [2.4K]

The surface area of the sphere is given by the equation

A=4\pi * r^{2},

where A is the surface area and r is the radius.

We want to find the volume of the sphere, which is given by the equation

V = \frac{4}{3} * \pi * r^{3},

where V is the volume and r is the radius.

Looking at these equations, we see that they both involve the sphere's radius. If we know what r is, we can calculate the volume.

We know that the sphere's surface area is 36 \pi. Plugging that in for A in the surface area equation, we get

36 \pi=4\pi * r^{2}, then divide by \pi

36 = 4 * r^{2}, then divide by 4

r^{2} = 9, then take the square root of both sides

r = 3

So the radius of the sphere is 3. Plugging this into the volume equation,

V = \frac{4}{3} * \pi * 3^{3}, simplify terms

V = \frac{4}{3} * \pi * 27, multiply \frac{4}{3} by 27

V = 36 * \pi

So the volume of the sphere is 36\pi.

Brilliant_brown [7]

Answer:

120 feet by 100 feet

Step-by-step explanation:

6 divided by .5 equals 12. Multiply 12 times 10 to get the length of 120 feet.

5 divided by .5 equals 10. Multiply 10 times 10 to get the width of 100 feet.  

I hope this helps! If you need further explanation let me know.
