Area of shaded portion = area of circle 1 - circle 2
Pi r*2 - pi R*2 =
Pi (r*2 -R *2 ) = 9*2 - 5*2 = (pi)81- 25= 56 x 3 = 168
Find the area of the base:
(4)(3) = 12sqft
Find the area of the sides:
(4)(12) = 48sqft
There are 2 bases and 4 sides, therefore:
12(2) + 48(4) = 24 + 192 = 216sqft
Hope this helps :)
Answer: 5 pounds
Step-by-step explanation: 90 - 47.65 ÷ 8.47 = 5
3p² - 2p - 5 = 0
3p² + 3p - 5p - 5 = 0
3p(p + 1) -5(p + 1) = 0
(3p - 5)(p + 1) = 0
p = 5/3 or -1
Hope this helps!
