Answer:

C, C and A

Step-by-step explanation:

using the formulae relating to the circle

• Area (A) = πr² ( r is the radius )

• Circumference (C) = 2πr ( r is the radius )

(8)

Area of the interior with r = 4

A = π × 4² = 16π ≈ 50.27 ft² → C

(9)

Area of exterior with r = 7

A = π × 7² = 49π ≈ 154 ft² → C

(1)

Circumference of exterior circle with r = 7

C = 2 × π × 7 = 14π ≈ 44 ft → A
