Answer:
113.1 cm³
Step-by-step explanation:
The volume of a sphere of radius r is V = (4/3)πr³.
If the radius is 3 cm and the answer is to be expressed to the nearest tenth, then we get:
V = (4/3)(3.14159)(3 cm)³
= (4/3)(84.82 cm³
= 113.1 cm³
113 cm^3
The formula for volume of a sphere: 4/3*pi(usually in 3.14)*radius^3.
So you just plug in the values. 4/3 times 3.14 times 27 which equals to 113.04 cm to the power of 3. You get 27 from 3 cube. Don't forget to write the unite which is cm^3
