Question

A large drum is constructed with a diameter of 14.66ft. What area of the circular face of the drum? What is the circumference of the drum? Use 3.14 as an approximation for pie symbole

Answer 1

Use the formula for area of a circle.

 

A = 3.14(d/2)²

 

A = 3.14(d² / 4)

 

A = (1/4)(3.14d²)

 

To find circumference of circle,

 

C = 3.14d
