What is the circumference of a circle with a radius of 80 inches? (use pi = 3.14)

The  circumference  of given circle = 502.4 inches

Step-by-step explanation:

Formula:

Circumference of circle = 2πr

Where r - Radius of circle

and π is a constant value

To find the Circumference of circle

Here

radius r = 80 inches and

π = 3.14

Circumference = 2πr = 2 * 3.14 * 80 = 502.4 inches

Therefore Circumference  of given circle = 502.4 inches

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
