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
