Question

What is the best approximation for the circumference of a circle with a radius of 125 m?

Answer 1

Forumla for circumference is
pi x diameter
or
 pi x 2 x radius
so we are going to use the second formula to estimate the answer without a calculator.
3 x 2 x 125
3 x 2 =6
6 x 125 = 750.
the closest answer is 785m. That is the answer.

Answer 2

Answer:

(B) 785m

Step-by-step explanation:

It is given that the radius of the circle is 125m and we have to find the circumference of the circle.

Then, the circumference of the circle is calculated as:

Circumference=$2{\pi}r$

Circumference=$2(3.14)(125)$

Circumference=$785m$

Thus, the circumference of the circle is 785m.
