Answer:
The answer for part A is 49π cm² and part B is 81π in².
Explanation:
In part A, 14cm represents the length of diameter of circle, in order to find its radius, you have to divide it by 2 which is 7cm. Next, you have to apply area of circle formula :
A = π × r²
A = π × 7²
A = 49π cm²
Part B :
A = π × 9²
A = 81π in²
