Find the circumference and area of the circle if d equals 30 Use n equals 3.14?
The circumference of a circle is 2 * r * pi or d * pi; the diameter "d" = 2* the radius "r". "pi" is - VERY approximately! - 3.14. The area of a circle is pi * r^2. There is a calculator built into Windows, or you can use the calculator built into Google.
If the area of a circle is 25 square units what is the radius of the circle?
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
Is c equals 2πr the same as c equals πr squared?
No. C = 2*pi*r is the equation representing the circumference of a circle. The area of a circle is equal to pi*(r^2).
What is the area of a circle if the r equals half?
Area = pi*0.52 = 0.785 square units to 3 d.p.
Area of a circle with a radius of 12?
Area of a circle = Pi times r^2. r=12 A = pi x (12^2)= pi x 144 equals approximately 452.3893421
What is the area of a circle if r equals 9 yd?
r=9yd
How do you fin the area of a circle?
The area of a circle equals pi x r squared or A = pi x r2 A = area of circle pi = approximatley 3.14 r = radius

What is the area of a circle if r equals 2cm?
If r = 2 cm, then A = 12.6 cm2
What is the area r equals 3 in?
The area of a circle is pi r2 If r = 3, that makes the area roughly 28.27
What is the formula for the area of a circle if the R equals 12?
Area = pi*122 measured in square units
Is c equals 2πr the same as c equals πr squared?
No. C = 2*pi*r is the equation representing the circumference of a circle. The area of a circle is equal to pi*(r^2).
What is the area of a circle if the radius equals 15 cm?
area=pi*r*r area=(22/7)*15*15 area=707.14 square cm
What is the area of a circle if the r equals half?
Area = pi*0.52 = 0.785 square units to 3 d.p.
Area of a circle with a radius of 12?
Area of a circle = Pi times r^2. r=12 A = pi x (12^2)= pi x 144 equals approximately 452.3893421
What is the formula for the surface area of a circle?
The formula for the surface area of a circle is pi times the square of the radius. It is represented as A equals pi times r squared.
