A certain coin is a circle with diameter 42 mm. What is the exact area of each side of the coin? The exact area of each side of the coin is mm.
(Simplify your answer. Type an exact answer in terms of .)

The area of a circle is r^2 x PI

r is half the diameter = 21mm

Area = 21^2 x PI

area = 441pi

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

hope my answer has you!

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
