Answer: I replaced pi with 3.14 in my calculator just so you know.
Cylinder: 251.2, Cone 1: 83.7, Cone 2: 251.2, Sphere: 62.8, 25 times
Step-by-step explanation:
<em>Cylinder:</em>
Cylinder equation: volume = π · r2 · h
High 8, radius is 5-
π · 5 · 2 · 8 = 251.2
<em>Cone 1:</em>
Cone equation: volume = (1/3) · π · r2 · h
High 8, radius is 5
(1/3) · π · 5 · 2 · 8 = 83.7
<em>Cone 2:</em>
Cone equation: volume = (1/3) · π · r2 · h
High 24, radius is 5
(1/3) · π · 5 · 2 · 24 = 251.2
<em>Sphere:</em>
Sphere equation: volume = (4/3) · π · r3
Radius is 5
(4/3) · π · 5 · 3 = 62.8
<em>Amount times:</em>
62.8/83.7 = 0.75....
0.75 = 75%
100-75 = 25
I think it is 25, not 100% sure.
By the way im not 100% sure with my answers! But if this is right and you found this helpful that is all that counts!
When you mean estimate do you mean by rounding the first numbers?
Step-by-step explanation:
The total surface area is 168 square units.
