Q:
Find the area and perimeter of each composite figure use 3.14 for pi round your answer to the nearest 10thFind the surface area and volume of each figure use 3.14 for pi round your answer to nearest 10th I have examples if needed
Accepted Solution
A:
1. Perimeter is 3 + 3 +3 +4 +5 = 18 feet Area = 3*3 = 9, 1/2*3*4 = 6, 9 + 6 =15 square feet2. perimeter = 2.5 +2.5+ 2.5+2.5+0.5+0.5 = 11 meters Area = 3*.5 = 1.5, 3*2=6, 6+1.5 = 7.5 square meters3. perimeter = 3.14*2*3 = 18.84 +8 = 26.8 inches Area = 6*4 = 24 + 3.14*3^2 = 28.26 = 28.26 +24 = 52.3 inches4. surface area = 2*π*6*20+2*π*6^2= 980.2 yardsVolume = π*6^2*20 = 2261.9 cubic yards5.surface area = 2*(9*7+2*2+2*9) = 190 cm Volume = 2*7*9 = 126 cubic cm6. surface area = 2*(11*11+11*11+11*11) = 726 mm Volume = 11 *11*11 = 1331 cubic cm
