Vol of sphere =4/3πr³
let the radius of cone be x.
vol of cone =1/3πx²h
when h=r, =1/3πrx²
since they have the same volume,
4/3πr³=1/3πrx²
4πr³=πrx²
x²=4r²
x=2r (radius)

If you subtract for 4 from 7 in the first expression, then h is less than or equal to 3.

If you subtract 1 from 3 in the second expression then h is greater than 2.

Thus the only value of h possible is 3.

The blue segment below is a diameter of 0. What is the length of the radius of the circle

Norma-Jean [14]

Answer:

Option (B) 5.1 units

Step-by-step explanation:

Since the radius of the circle is half of its diameter and given the diameter of the circle is 10.2 units then the radius would be $\frac{10.2}{2} = 5.1 units$

Thus the answer.
