Step-by-step explanation:
Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
Answer:
The triangles have sides in 4:3 ratio.
Step-by-step explanation:
Largest side for each is 16 and 12. 16:12 = 4:3.
