Circumference circle = pi* r^2
Load and crunch
previous formula was for area.
The correct answer is 2*Pi*r = 24*Pi = 75.4 cm (rounded to nearest tenth).
I stand corrected. One needs be more careful. Thank you.
If 34 inches is the radius or diameter of the circle, (or circumference?), it needs to be stated in the question! What is meant by "round circle?"
Circumference of a circle = 2*pi*radius or pi*diameter
66 feet
Assuming the question refers to a circle with a diameter of 0.9 metres, the circumference is 2.83 m = 2.8 metres to the nearest tenth.
62.8-62.83cm
A circle with a radius of 4 units has a circumference of 25.13 units.
30.46 but round it to the nearest decimal and it will be 30.50
47.25
It depends on what the "32in" refers to: circumference, diameter, radius.
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 21.67698931 or 21.7 meters to the nearest tenth
The circumference of a circle with radius of 7 km is 44.0 km (to the nearest tenth), and the area of a circle with radius of 7 km is 153.9 km (to the nearest tenth).C = 2 pi RA = pi R2
-- Multiply (pi) by (diameter of circle)OR-- Multiply (pi) by (2 times radius of circle)-- Then round the product to the nearest whole number.
If you have the radius, then area = pi*r2 which you then round to the nearest hundredth. If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.
The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius. Given the radius as 47, the circumference would be C = 2 * 3.14 * 47 = 294.04. Rounding to the nearest hundredth, the circumference is approximately 294.04 units.
Radius is the distance from the centre of a circle to the outside The circumference of a circle is the distance round the outside of a circle
If 34 inches is the radius or diameter of the circle, (or circumference?), it needs to be stated in the question! What is meant by "round circle?"
If the circumference of a circle is 7 cm, the radius is 1.114085 cm, which rounds to 1.1 cm
