Answer:
210
Step-by-step explanation:
Your answer is 210. Assuming that the correctly formatted question is (7x10) 3, you would solve the problem like this.
First, always start with what's in parenthesis.
(7x10) = 70
Now that we have 70, we can multiply it by the remaining number, 3.
(70) 3 also known as 70x3 = 210.
Answer:
volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
Step-by-step explanation:
The formula to find volume of sphere is:
Volume of sphere = 4/3 π r^3
if radius is divided by 2 i.e r/2
Volume of sphere if r/2 = 4/3 π (r/2)^3
= 4/3 π r^3/8
= (4/3 π r^3) / 8
= (Volume of sphere 1)/8
So, volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
