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
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
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
How do you the the area of a circle with the radius being 2cm?
Area = pi*r^2 = 4*pi = 12.6 square cm rounded to 1 decimal place.
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.
Why is area of circle equals pi r squared?
Because a circle does not have length times width so pi is in it's place.
