Just use the formula for the area of a circle (pi x radius2). Don't forget to divide the diameter by 2, to get the radius.
-- Multiply (pi) by (diameter of circle)OR-- Multiply (pi) by (2 times radius of circle)-- Then round the product to the nearest whole number.
Diameter of circle: 792/pi = 252 inches to the nearest whole number
Circumference of circle: 57*pi = 179 mm to the nearest whole number
Circumference of circle: 14*pi = 44 units rounded to nearest whole number
Circumference of circle in inches: 108*pi = 399 inches to the nearest whole number
The area of a circle with a diameter of twelve inches rounded to the nearest whole number is 113 square inches.
The area of a circle with diameter equals 12 inches to the nearest whole number is: 113 square inches.
-- Multiply (pi) by (diameter of circle)OR-- Multiply (pi) by (2 times radius of circle)-- Then round the product to the nearest whole number.
Diameter of circle: 50/pi = 16 cm rounded to the nearest whole number
Diameter of circle: 792/pi = 252 inches to the nearest whole number
Diameter of circle: 25/pi = 8 inches rounded to the nearest whole number
Diameter of circle: 132/pi = 42 inches rounded to the nearest whole number
Circumference of circle: 57*pi = 179 mm to the nearest whole number
The diameter of the circle works out as 20 units to the nearest whole number
Circumference of circle: 14*pi = 44 units rounded to nearest whole number
Circumference of circle in inches: 108*pi = 399 inches to the nearest whole number
It depends on what the "32in" refers to: circumference, diameter, radius.
