The volume of a cylinder is 1,692.46 in cubed. if the radius becomes three times as large, what will be the cylinder's volume?

We know that
original volume of a cylinder=pi*r²*h
volume=1692.46 in³
1692.46=pi*r²*h

if the radius becomes three times as large
so
r=3*r
new volume=pi*(3*r)²*h> 9*pi*r²*h
new volume=9*original volume
new volume=9*1692.46> 15232.14 in³

the answer is
the new volume is 15232.14 in³

Your cleary not see the answer is 25

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
