Area = pi*r2 = 3217 sq inches to the nearest integer.
-- Multiply (pi) by (diameter of circle)OR-- Multiply (pi) by (2 times radius of circle)-- Then round the product to the nearest whole number.
47.25
It is: pi*15.42 = 745.06 square units
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 21.67698931 or 21.7 meters to the nearest tenth
radius is 5cm. pi x r2 is 78.54, /3, *2 is 52.36cm2
-- Multiply (pi) by (diameter of circle)OR-- Multiply (pi) by (2 times radius of circle)-- Then round the product to the nearest whole number.
It depends on what the "32in" refers to: circumference, diameter, radius.
30.46 but round it to the nearest decimal and it will be 30.50
A circle with a radius of 4 units has a circumference of 25.13 units.
26.7 mm
47.25
The area of a circle is: pi times radius squared
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.
It is: pi*15.42 = 745.06 square units
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
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 21.67698931 or 21.7 meters to the nearest tenth
If the circumference of a circle is 7 cm, the radius is 1.114085 cm, which rounds to 1.1 cm
