Find the area of the following circle. (round answer to the nearest whole number.) circumference = 280 cm. (hint: find r from c = 2πr (round r to tenths); then find area). 1) 89 2)560 3)1,989 4)6,246

4)6,246

Step-by-step explanation:

First we will find the value of r.

The formula for circumference is C = 2πr:

280 = 2(3.14)r

280 = 6.28r

Divide each side by 6.28:

280/6.28 = 6.28r/6.28

44.6 ≈ r

The formula for the area of a circle is

A = πr²

Using our value for r, we have

A = 3.14(44.6)² = 6245.9624 ≈ 6246

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
