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
For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.
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.
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
26.7 mm
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.
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

Circumference of a circle = 2*pi*radius or diameter*pi
