the circumference of a circle is about 53.38 cm. The radius of the circle is 8.5 cm. Which expression best represents the value of pi?

Step-by-step explanation:

Circumference of a circle is expressed as;

C = 2πr

r is the radius of the circle

Given

C = 53.38cm

radius r = 8.5cm

Substitute into the formula to get π

From the formula;

π = C/2r

π = 53.38/2(8.5)

π = 53.38/17

π = 3.14cm

The value of pi is 3.14 cm

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
