A circle has a circumference of 615.44 point, 44 units.<br> What is the radius of the circle?
Tpy6a [65]

The circumference of a circle is equal to C=2πr

From the question, we have 615.44.

Assume that pi is equal to 3.14

Substitute and solve for r

615.44= 2(3.14)r

r= 615.44/ 6.28

r=98.4704

r=98

Therefore, the radius is about 98 units.

To check:

C=2πr

C=2 x 3.14 x 98

C=6.28 x98

C=615.44

What is the APY of a savings account with an APR of 3.9742% compounded monthly? Answer to the four decimal place
Maurinko [17]

Answer:

The APY of the saving account is 4.0474%

Step-by-step explanation:

We know the formula for APY which is given by

APY=(1+\frac{r}{n} )^n-1

here, r= interset rate =  3.9742% = 0.039742

n = compounding cycles = 12

On plugging these values in the above formula, we get

APY=(1+\frac{0.039742}{12} )^{12}-1

On simplifying this we get

APY =0.04047395=4.0474%
