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
A circle with a radius of 126 km has a circumference of 791.68 km.
Oh, dude, you're hitting me with some math here. So, the circumference of a circle is calculated by multiplying the diameter by pi (π). Since the diameter of a circle is twice the radius, and you've given me the radius (40 mm), I can tell you that the circumference of a 40 mm circle would be approximately 251.2 mm. It's like math, but with a side of sarcasm.
7 7 x 126 cm = 9,702 cm = 97.02 metersThis could have been a much more interesting problem if you had giventhe diameter of the wheel instead of its circumference.
Total surface area is 226 square inches and the curved surface area is 126 square inches.
126 inches is 10 feet 6 inches.
126 inches is 3.5 yards.
There are 12 inches in one foot. Therefore, 126 inches is equal to 126 / 12 = 10.5 feet or 10 feet 6 inches.
there are 36 inches in a yard so there are 126/36 yards in 126 inches. 126/36 = 63/18 = 7/2 = 3.5
Area of a circle = pi*radius2
126 inches is 3.5 yards.
126 millimeters is 4.96 inches.
Answer: 126 " = 3.5 yds.
