circumference is π*d. In this case it is 8π feet ≈ 8 * 3.1416 ≈ 25.1327 feet■
circumference formula is pi(diameter) diameter is 2(radius) radis=4; diameter=2(4)=8 pi(8)=circumference of the circle...this is the EXACT answer plug it into a calculator and you will get 25.1327412287 your welcome ;)
If you're talking about the radius being 24 cm, then the the circumference is exactly 48 PI. If the diameter is 24 cm, then the circumference is 24 PI
circumference = 2πr = 2π x 6 = 12π units
Well, honey, the circumference of a circle is calculated using the formula C = 2πr, where r is the radius. Since you didn't give me the radius, I can't give you the exact circumference. But if the diameter is 56 cm, then the radius would be half of that, which is 28 cm. Plug that into the formula and you'll get your answer.
pi times the diammeter 3.14159 x diameterDan's answer:circumference= pi X diameter.2pi X Radius=Pi X Radius (x2)
the exact circumference is 11pi inches
Circumference of the circle: 7.4*pi cm
31x3.1416=circumference
65.94
150.8
Approx. circumference = multiply diameter by 22 and divide the product by 7. Exact circumference = Pi x diameter.
-- Exact circumference = 2pi meters -- Approximate circumference = 6.283 meters
The circumference of any circle when divided by its diameter has the exact value of pi
(circumference=2πr or πd) so the circumference in exact form would be π726.4
circumference formula is pi(diameter) diameter is 2(radius) radis=4; diameter=2(4)=8 pi(8)=circumference of the circle...this is the EXACT answer plug it into a calculator and you will get 25.1327412287 your welcome ;)
Oh, dude, you're hitting me with some math right now? Okay, so the circumference of a circle is π times the diameter, which is 16.8. So, it's like 16.8 times π. If you want an exact answer, it's around 52.88 units. But who's counting, right?
They put the value of pi as about 3 but even today we do not know its exact value only that the circumference of a circle divided by its diameter is equal to pi
