The circumference of a circle is 31.4 feet. what is the area?

A ≈ 78.46 ft

To find the answer just look up the formula for finding area with circumference and plug in the circumference

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
