You can use the formula A = C/4 to find the area of a circle given the circumstance. Describe another way to find the area of a circle when given the circumstance. Help please!

Step-by-step explanation:

Given

Describe another way to get area from circumference

Circumference C is calculated using:

Area, A is calculated using:

Using:

Divide both sides by 2

Multiply both sides by r

The expression on the right-hand side is the area.

So, substitute for A

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
