What is the surface area of half a sphere?
its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
What is the rule for pie r squared?
Area of a circle = pi*radius2
Why is it pie r squared is the exactly formula for circumference?
It isn't. That is the formula for the AREA of a circle!
How do you calculate the area of circle?
Area: (pi)(r)2
What is the area of a circle that has a radius of 4?
PIE r squared 3.142 X 42 = 50.24
What is the surface area of half a sphere?
its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
Pie squared plus pie squared divied by 2?
if you mean PI squared + PI squared / by 2 then that is.... 4.9298 solved on paper ... BUT if you mean what you said, the answer is YUMMY!
How do you a just the circumference of a circle?
pie r squared
What is 2 pie r sqaured?
Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
How do you find area of a cylinder?
(2)(pie)(r)(h) + (2)(pie)(r - squared) = tot area of a cylinder
What is the value of r³?
As in pie r squared? r = radius.
Find the radius of a circle if its area is 254.5 square inches?
The formula for the area of a circle is pie r squared therefore if pie r squared = 254.5 r squared = 254.4 divided by pie = 81.009... r = square root of 81.009... = 9.000... = 9 ( correct to the nearest whole number) therefore radius of this circle is 9
What is the rule for pie r squared?
Area of a circle = pi*radius2
What is pie 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)
Why is it pie r squared is the exactly formula for circumference?
It isn't. That is the formula for the AREA of a circle!
What is the formula for calculating the area of a circle?
Area of circle = pie x (r squared) = πr^2 r = radius π = pie = 22/7 or 3.142
How do you calculate the area of circle?
Area: (pi)(r)2
