Answer:
15π/2 ft
Step-by-step explanation:
Arc length is given by the formula ...
s = rθ . . . . . r = radius; θ = central angle in radians
A 135° arc has a radian measure of (135)(π/180) = 3π/4. The radius of a circle with a 20 ft diameter is (20 ft/2) = 10 ft. So, the arc length is ...
s = (10 ft)(3π/4) = 30π/4 ft = 15π/2 ft
surface are is basically the area of all the shapes in the prism, so :
(2 x area of the triangles on the sides) + area of upper rectangle + area of bottom rectangle + area of side rectangle
(2x((1/2) x 12 x 5)) + (13 x 10) + (12 x 10) + (10 x 5)

Nvm wait I read the question wrong. The real answer would be 28, 28, 36
Answer:
2700 cubic feet
Step-by-step explanation:
Volume=lenght*width*height
22*10*11=2420
10*7*4=280
2420+280
