Answer:

65.94

Step-by-step explanation:

Find the area of the smaller circle and subtract it from the area of the larger circle. This is the area of the shaded region.

Larger Circle - If d = 12.5, then the radius r = 6.25.

Area = π(6.25)² = 122.66

Smaller Circle - If d = 8.5, then the radius r = 4.25.

Area = π(4.25)² = 56.72

Shaded region - 122.66 - 56.72 = 65.94

Answer:

65.94 cm²

Step-by-step explanation:

12.5/2 = 6.25 = radius of large circle

8.5/2 = 4.25 = radius of small circle

A= πr²

A of large circle = 3.14(6.25²) = 122.66

A of small circle = 3.14 (4.25²) = 56.72

122.66 - 56.72 = 65.94 cm²

Anestetic [448]

Answer:

see explanation

Step-by-step explanation:

the perimeter is the sum of the 3 sides of the triangle

add the parts of the ratio 21 + 8 + 14 = 43

divide the perimeter by 43 to find the value of one part of the ratio

\frac{215}{43} = 5 ft ← 1 part of the ratio, hence

21 parts = 21 × 5 = 105 ft

8 parts = 8 × 5 = 40 ft

14 parts = 14 × 5 = 70 ft

the 3 sides of the triangle are 105 ft, 40 ft and 70 ft
