Yes, it is.
Hint, always remember to check that the figure given in the problem is the radius., and not the diameter. If it is the diameter, then the radius is half that.
no
Pi r squared comes from the formula to find the area of a circle.
Pi times r times r or Pi r squared is the formula for finding the area of a circle where r is the radius
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
pi times r squared
Pi x radius(R) squared e.g radius of circle is 5cm A=3.14x5 squared Area is 78.5
The area of a full circle is pi x R squared where R = RADIUS The area of a semi circle is half of that, or pi x R squared/2
the area of a circle
A=pi(r)squared
"Pi R Squared" refers to the formula for the area of a circle. A = (pi)r2 (3.1416 times the square of the radius)
Area of a circle = pi*radius2 measured in square units
pi times the radius squared pi r squared
Area = pi*radius2A = Pi*R-squaredPi * R^2
area=pi r squared
The area of a circle = pi*r2
Yes.
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
