Does anyone know the volume?

2048π/3

or 2144.6606

Step-by-step explanation:

The formula to find the volume of a sphere is

V=4/3πr^3

To find the solution, plug in the value of the radius, 8

V=4/3 * π * (8^3)

Then solve by combining 4/3 and π to get, 4π/3 and raise 8 to the power of 3 to get 512. You would then get

4π/3 * 512

Multiply that to find the solution of

2048π/3

or 2144.6606

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
