a round mirror has a circumference of 87.92 inches. calculate the area of the mirror. use 3.14 for pi. round answers to the nearest hundreth if necessary

615.44 in²

Step-by-step explanation:

Use the circumference formula, C = 2r

Plug in the circumference and pi to solve for the radius, r:

C = 2r

87.92 = 2(3.14)r

87.92 = 6.28r

14 = r

Then, use the area formula, A = r²

A = 3.14(14)²

A = 615.44 in²

So, the area of the mirror is 615.44 in²

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
