a. Area = 1,017.36 cm²; Circumference = 113.04 cm

b. Area

c. Circumference

Step-by-step explanation:

Given:

Radius (r) = 18 cm

π = 3.14

a. Area of the mirror = area of circle = πr²

Plug in the values

Area = 3.14*18²

Area = 1,017.36 cm²

Circumference = 2πr

Circumference = 2*3.14*18

Circumference = 113.04 cm

b. The area of the glass would be used in finding the amount of glass needed caused it's the surface of the glass that is to be replaced.

c. The silver wire would be placed around the mirror, therefore, it is the circumference that would be needed in finding the amount of wire needed since the circumference is the perimeter round the mirror.

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
