Answer:

Step-by-step explanation:
We have the cone and the half-sphere.
The formula of a volume of a cone:

r - radius
H - height
We have r = 7cm and H = (22-7)cm=15cm. Substitute:

The formula of a volume of a sphere:

R - radius
Therefore the formula of a volume of a half-sphere:

We have R = 7cm. Substitute:

The volume of the given shape:

Substitute:

45
15 is a multiple of 3
30 is a multiple of 3
45 is NOT a multiple of 3
60 is a multiple of 3

Answer:
x = 24
Step-by-step explanation:
Given that:
(x+3)/3 = 9
multiplying both sides by 3
(x+3) = 9*3
(x+3)= 27
Subtracting 3 from both sides
x= 27-3
x=24
I hope it will help you!
First you will divide 525 by 100. Then you multiply your answer by 4. That will equal 21
