Answer:
1. 800 cm squared
2. 152 cm squared
Step-by-step explanation:
let break it down
1. 800 cm squared
20 * 7 = 140
20 * 6 = 120
38 - 20 = 18
30 * 18 = 540
now add all of them together
140 + 120 + 540
100 + 100 + 500 = 700
40 + 20 + 40 = 100
700 + 100 = 800 cm squared
2. 152 cm squared
16 * 10 = 160
2 * 2 + 2 * 2 = 4 + 4 = 8
160 - 8 = 152 cm squared
Answer:
11.5 cm^3
Step-by-step explanation:
The volume of a sphere is (4/3)(pi)(r^3). To find the radius, divide the diameter of 2.8 to get 1.4. Then plug it in to get 11.49. 11.49 rounded to the nearest tenth is 11.5 cm^3.
