The answer is 457 because when you add 381 and 76 together you get 457
56.52 ÷ pi(3.14) = 18
18 ÷ 2 =9
A = pi(3.14)r^2
A = 3.14 × 9^2
A = 3.14 × 81
A = 254.34in^2
Answer:
8 ft
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
Arc length = radius × angle
s = r θ
60 cm = 20 cm × θ
θ = 3 radians
Answer:
arc FD = 236°
Step-by-step explanation:
The measure of the arc is equal to the measure of the central angle it subtends, thus
arc FD = arc FE + arc ED = 146° + 90° = 236°
