The volume of a cylinder is equal to h*pi*r^2 where h is height and r is radius. We are given everything we need to solve for the radius.
176pi = 11pi * r^2
176 = 11r^2
176/11 = r^2
r = sqrt(176/11) = 4 cm
Answer:
gvhbh
Step-by-step explanation:.
The equation for this is:
F = P(1+i)ⁿ
where
F is the present accounts balance
P is the initial deposit
i is the interest rate
n is the number of months
The interest rate is nominal which is 2.9% per year compounded monthly. Since there are 12 months in a year, that is equal to an effective interest rate of 0.24167% per month compounded monthly (i = 0.0024167). In 9 years, there are a total of 108 months, so n=108.

P = $1567.147
The formula is a permutation in which n represents the sample points in the set, while r represents the number of sample points in each permutation.
