Given radius=15 inches
Perimeter=circumference of circle
Circumference=2 pi r
=pi=22/7 or 3.14
=2*3.14*15=94.2
Rounded off=100
SOLUTION
Given the question in the question tab, the following are the solution steps to answer the question.
STEP 1: Write the formula for calculating compound amount

where
A = final compounded amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
STEP 2: Write the given data
Semiannually means that n will be 2

STEP 3: Calculate the compound amount

Hence, the compounded amount after 4 years is $18,748.1972

Hello from MrBillDoesMath!
Answer:
$3.25
Discussion:
Money spent = paperback's purchased + hardback's covered =
3 (0.25) + 5 (0.50) =
0.75 + 2.50 = $3.25
