Find the exact circumference of a circle with the given radius. x/2 miles c =
¼x miles x miles 2x miles

x miles

Step-by-step explanation:

Circumference, C= 2

r=radius = x/2

C= 2× × x/2

C= x

πx miles

Step-by-step explanation:

Given in the question,

radius of a circle = x/2 miles

To find circumference of a circle we will use following formula

2π * r

where π is constant = 3.14

            r is radius of circle

Plug values in the formula

2(3.14)(x/2)

2 will cancel out

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.
