The circumference of a pizza is 75.36 in. What is the approximate area of the circle? Answers A.(113.04 in2)
B.(37.68 in2)
C.(1808.64 in2)
D.(452.16 in2)

Answers

Circumference = diameter x pi

Find the diameter:

75.36 = diameter x pi

Divide both sides by pi:

Diameter = 75.36/3.14 = 24 inches.

Area = pi x r^2

R = 1/2 diameter = 12

Area = 3.14 x 12^2

Area = 452.16 in^2

The answer is D.

Emilee put 3000 in a 2 year cd paying 4% interest, compounded monthly. After 2 years, she withdrew all her money. What was the amount of the withdrawal?

Answers

Answer:

3249.43

Step-by-step explanation:

The monthly compound interest can be determined from the following formula:

$A=P*(1+r/n)^(n*t)$

Where A is the final amount after interest, P is the intital amount invested, r is the interest rate, n is number of times interest is compounded per year, and t is the time in years.

We need to express rate as abn equivalent decimal number:

$4/100=0.04$

∴ $A=3000*(1+0.04/12)^(12*2)=3249.43$

3,000×(1+0.04÷12)^(24)
=3,249.43
