Step-by-step explanation:

The volume of a sphere is found by

The radius is 7 so this should give you (4/3)pi(7)^3

(4/3)pi(343)

Hopefully this is the format it is in... Hope this helps :)

1372

Step-by-step explanation:

Volume of a sphere can be found by using the formula V= 4/3 () where r is the radius of sphere.

Thank me or give 5 stars if you learned! Or if it is correct!

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
