Best Answer

The formula for circumference of a circle is pi*d or 2(pi)r

The first is better since we already have the diameter.

To solve this, simply multiply the two

You can leave your answer was 12.6(pi) or make pi equal to 3.14 (not prefered, but ok for beginners)

If you did choose to do this, you would get 39.564

Area of a circle = pi*radius2

Answer: 126 " = 3.5 yds.

There are 2.54 centimetres in one inch. Therefore, 126 inches is equal to 126 x 2.54 = 320.04 centimetres.

1 yard = 36 inches 3 yards = 3*36 = 108 inches 3 yards 18 inches = 108+18 inches = 126 inches

126 inches. 12 inches = 1 Foot 3 Feet = 1 Yard 3.5 * 3 * 12 = 126
