Question

The radius of Venus is 3,760.4 miles. What is the approximate volume of Venus?

Answer 1

The volume of a sphere is given by the formula V=(4/3) π r³ 

The approximate volume of Venus is therefore 
V = (4/3) π 3760.4³ mi³ 
V = 70,899,123,900π mi³ 

Substituting π=3.14, 
V = 70,899,123,900 (3.14) mi³ 
V = 222,623,249,046 mi³ 

In scientific notation, 
V = 2.2 x 10¹¹ mi³
