7. what is the racis of a sphere that has a volume of
288pie?
a. 3
b. 4
c. 5

Radius of a sphere=6

Step-by-step explanation:

Volume of a sphere is given by

V=4/3πr³, where

V is the volume, π is a constant pi,and r is the radius of the sphere

Given, Volume (v)=288π, substitute in the formula:

288π/π=(4/3)πr³/π

288=(4/3)r³

r³=(288×3/4)=216

r³=216,to solve for r we get the cube root of r³ and 216

∛r³=∛216

r=6

The radius of a sphere=6

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
