A. 6 because 30/5= 6
B. She has gotten 35 points because 7*5=35
48 inches to 30 inches is a decrease.
percent decrease = change/original value x 100%
= (48 - 30)/48 x 100%
= 18/48 x 100%
= 37.5% decrease
To find markup price, multiply the original number (455) by 1 + the decimal equivilent of the percent increase (.34)
so
455*1.34= $609.70
Well, that means that the sides and top are toutching the sphere
radius of sphere=10 so radius of cylinder=10
the height is the diameter or 20
V=hpir^2
v=20pi10^2
v=20pi100
v=2000pi
answer is D
