Answer:
The first one is 20, second is 5 3/5, the third one should be 22.8, fourth is 1, fifth is 15.9
Step-by-step explanation: Add all the numbers up (for each shape). For the parallelogram multiply the top and right sides by two.
Answer:
1. a= 68 b= 112 c= 68
2. a= 127 (Therefore you're correct)
3. a= 35 b= 40 c= 35 d= 70
Step-by-step explanation:
Number 3 would need to equal 360
Answer:
113.04 cubic inches
Step-by-step explanation:
V=π * r^2 *(h/3)
V= 3.14 * 36 * (3/3)
V = 3.14 * 36 * 1 = 113.04
Answer:
Radius of the sphere = r
<u>Volume of sphere:</u>
Radius of the hemisphere = 2r
<u>Volume of the hemisphere:</u>
- V₂ = 1/2×4/3×π(2r)³ = 1/2×8×4/3πr³ = 4V₁
The volume of the hemisphere is 4 times greater than the volume of the sphere
