Answer:
325pi m^3
Step-by-step explanation:
diameter of the base = 10 m
radius of the base = diameter/2 = 5 m
volume of cylinder = (pi)r^2h
Since the problem asks for the exact volume, we keep pi as pi, and we do not use an approximation of pi such as 3.14
r = 5 m
h = 13 m
volume = (pi)r^2h
volume = (pi)(5 m)^2(13 m)
volume = 25 * 13 * pi m^3
volume = 325pi m^3
Hi. Is the (.2t-1) supposed to be squared anywhere due to acceleration being rated with respect to time squared...? If not, all you have to do is create an equation:

Then, you factor out all those parts within the parenthesis to that 12.5, giving you:

Move all non-t values to the numerical side:

divide both sides by the coefficient of the variable t, and that will be your time, 7.186
Answer:
3602.
Step-by-step explanation:
The formula is:
Population after n years = 2000( 1.04)^n
After 15 years the population will be 2000(1.04)^15
= 3602.
1/4 of a mile times 9 equals 9/4 miles in total.
The horses time was 2.5 minutes.
Her average speed is distance/time.
9/4*1/2.5=9/10
Her average speed was 9/10 of a mile per minute.
