Question

if you had a radius of 2.5 and the second radius of the same shape is twice that which is 5 right what would the third radius be

Answer 1

The sphere below has a radius of 2.5 inches and an approximate volume of 65.42 cubic inches A second sphere has twice the radius of the given sphere. A third sphere has a diameter that is three-fourths of the diameter of the given sphere

Answer 4

first find the diameter of the original sphere

Answer 5

2.5*2

Answer 6

ok how do I do that

Answer 7

2.5 + 2.5

Answer 8

diameter = radius x 2

Answer 9

ok so I got that so wouldn't it be 3*2.5

Answer 10

2 * 2.5

Answer 11

ok I got that but for the third one wouldn't it be 3*2.5

Answer 12

the diameter of the first one is 5
the diameter of the third sphere is 3/4 the diameter of the first one

Answer 13

your question states:
The sphere below has a radius of 2.5 inches and an approximate volume of 65.42 cubic inches A second sphere has twice the radius of the given sphere. A third sphere has a diameter that is three-fourths of the diameter of the given sphere

Answer 14

A third sphere has a diameter that is three-fourths of the diameter of the given sphere

Answer 15

the diameter of the given is 5 so multiply 5*0.75 = 3.75

Answer 16

to find the radius, divide the diameter by 2
3.75/2

Answer 17

k thanks

Answer 18

so what's the radius of the third sphere?

Answer 19

1.875

Answer 20

correct
that's your answer

Answer 21

thanks
