Answer:
C
Step-by-step explanation:
The volume (V) of a sphere is calculated using the formula
V = 
πr³
If the radius is doubled, that is r = 2r , then
V = π (2r )³
(2r)³ = 8r³, thus the volume is multiplied by 8
Answer:
4 dollars
7 dimes or $4.70.
Step-by-step explanation:
The 4 dollars, 12 dimes, and 10 pennies added up together is $5.30. You will subtract that from $10.00 and you will get $4.70. That will be 4 dollars and 7 dimes left that is needed, or $4.70.
Answer:
2009cm^2
Step-by-step explanation:
Given data
let the length be L
and the width be w
so
w= x
L=x+8
P= 180cm
P= 2L+2W
180= 2(x+8)+2(x)
180= 2x+16+2x
collect like terms
180= 4x+16
180-16= 4x
164= 4x
x= 164/4
x=41
W= 41cm
L= 41+8
L= 49cm
A= L*W
A=49*41
A=2009cm^2
Hence the area is 2009cm^2
