Explanation:

What is the approximate area of the circle? (Use 3.14 for ).

A.3,017.54 cm?

B. 12,070.16 cm?

C. 194.68 cm2

D. 754.385 cm?

Answer 2

Hello!

To find the area, we use the formula A=pir², where pi=3.14 and r= the radius.

To solve, we find half of the diameter, which is the radius. Half of 53 is 26.5. We square this number and then multiply it by pi. 26.5·26.5=702.25. Now we multiply by pi. 702.25·3.14=2,205.065.

Our final answer is about 2,205.1 cm².

I hope this helps!
