Acircle has a radius of 26.85 inches. what is the circumference of this circle? use 3.14 for pi. round your final answer to the nearest tenth. enter your answer as a decimal in the box.

The circumference formula is

where r is the radius given to us as 26.85, and pi is to be 3.14. In our formula then, we have

.

Doing that multiplication and rounding to the nearest tenth leaves us with a circumference of 168.6 inches.

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
