The formula of interest is
A = (1/2)r²·θ
You have r = 9 m, θ = 3π/5. Then the area is
A = (1/2)(9 m)²(3π/5) = 24.3π m²
The sector area is ...
A ≈ 76.3 m²

Answer:
107.2 seconds
Step-by-step explanation:
Step one:
given
the diameter of ball 8 inches
radius= 8/2 = 4 in
The volume of the ball


Step two:
we know that
rate= quantity/time
rate= 2.4 in per second
quantity= 268.12
time=?
time= quantity/rate
time= 268.12/2.5
time= 107.2 seconds
Answer: 3.2 qts
Step-by-step explanation:
A=1/2 * b *h
1/2 * 4*8 = 16 square foot
Area is 16 square foot
Multiply the area by the quarts of paint it takes to cover 1 square foot.
16 * 0.2 = 3.2 qts
