Volume of a cylinder = πr²h

Given radius r = 6.5m

Height h = 17m

Volume = π × 6.5²×17

Volume = 3.14×6.5²×17

Volume of the cylinder = 2255.31cu.m

Beth will borrow $10,000 which earns 4% compound interest and she will repay that amount in 20 years. How much interest was earn

Serggg [28]

Answer:

$I=\$11,911.23$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the amount that she will repay

P is the amount borrowed

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=20\ years\\ P=\$10,000\\ r=0.04\\n=1$

substitute in the formula above

$A=10,000(1+\frac{0.04}{1})^{1*20}$

$A=10,000(1.04)^{20}$

$A=\$21,911.23$

Find out the interest

$I=A-P$

substitute the values

$I=\$21,911.23-\$10,000=\$11,911.23$
