What is the area of a circle with a radius of 42 inches?

5538.96 square inches

Step-by-step explanation:

Area of a circle = pi r^2

Given radius r = 42 inches and pi = 3.14

Area = 3.14 x (42)^2

= 3.14 x (42 x 42)

= 3.14 x 1764

= 5538.96 square inches

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

45
