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
area=pi r squared the r is the radius which is half of the diameter so area =pi mulitplied by 45 squared which is 6361.725124mm
Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h
pi times the radius squared pi r squared

pi*r squared:2 *=multiply : =divide
pi (muliplied by)r squared multiplied by the height r is the radius of the circle (half the diameter) so basically: pi x r x r x height
Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h
The area of a circle is pi multiplied by "'r' (radius) squared""r" is 2.5 (half of the diameter)"r squared" is 2.5*2.5 which is 6.25.In terms of pi, the area of the specified circle is 6.25[pi] units squaredPi's rounded answer is 3.14. So in an answer not in terms of pi, you would multiply 6.25 and 3.14. That equals 19.625 units squared
pi times the radius squared pi r squared
that is 14,519.4 squared
That is the formula for the area of a circle; r refers to the radius, and pi is approximately 3.14. r squared means that you multiply r x r.
"Pi R Squared" refers to the formula for the area of a circle. A = (pi)r2 (3.1416 times the square of the radius)
Pi times r times r or Pi r squared is the formula for finding the area of a circle where r is the radius
