If someone could answer and explain this that would be great! TYSM guys! <3

Answer 1

Answer:

The answer for part A is 49π cm² and part B is 81π in².

Step-by-step 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

Answer 2

Answer:

a. 49π

b. 81π

Step-by-step explanation:

formula is πr^2

find the square of the radius of the circle and then multiply by π.
