Question

The circumference of a circle is 15 pie centimeters. What is the area of the circle in terms of pie

Answer 1

Answer:

b

Step-by-step explanation:

Answer 2

Answer:

C

Step-by-step explanation:

The circumference (C) of a circle = 2πr ← r is the radius

Given C = 15π the equating gives

2πr = 15π ( divide both sides by 2π )

r = $\frac{15}{2}$ = 7.5 cm

The area (A) of a circle is calculated using the formula

A = πr² = π × 7.5² = 56.25π cm² → C
