The term "pi squared of circle 4" is not a standard mathematical phrase, but if you're referring to the area of a circle with a radius of 4, you would use the formula (A = \pi r^2). For a circle with a radius of 4, the area would be (A = \pi \times 4^2 = 16\pi). If you meant something else by "pi squared," please provide more context for clarification.

What is the diameter of the circle that has a circumference equal to its area?
The diameter is 4 and its radius is 2 because 2+2 = 4 and 2 squared = 4 Circumference of the circle: pi*4 is the same as pi*2 squared Area of the circle: pi*2 squared
How do you find the area of a sphere?
4 * pi * radius * radius or (pi * diameter * diameter) / 3 Also ( 4 * 3.14 * radius squared ) Also ( 88/7 * radius squared )
What is the answer of pi squared?
pi squared = approximately 9.8696044
What is pi squared times pi?
n squared x n = n cubed but that does not equal 21. ---------------------------------------------------------------- Here is the correct version: We are looking for Pi squared times Pi which is Pi cubed Now Pi can never be written out exactly because its decimal number goes on for ever. However we can take a good approximation to Pi as 3.142 So Pi cubed = 3.142 x 3.142 x 3.142 = 31.018339 = 31.02 to 4 places.
Does sphere have a surface?
Yes and its formula is: 4*pi*radius squared
The formula for circumference of a cirle is?
pi*radius squared
How do you find the area of a cirle with the circumference?
Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.
What is the area of a circle with radius 2?
To find the area of a cirle you multiple pi (3.14) by the radius squared, so you would have to find 3.14 times 4, which is 15.7.
What is the formula for the circumference of the cirle?
circumference of a circle = 2*pi*radius or pi*diameter
What is the diameter of the circle that has a circumference equal to its area?
The diameter is 4 and its radius is 2 because 2+2 = 4 and 2 squared = 4 Circumference of the circle: pi*4 is the same as pi*2 squared Area of the circle: pi*2 squared
What is the circunference of a cirle with 12 diameter?
circumference = pi*diameter
What is the diameter of a circle is the area is 400pie?
area = pi x diameter squared/4 = 400 pi diameter squared = 4 x 400 x pi/pi = 1600 diameter = sqrt 1600 = 40
What is 4 times pi times the radius squared is the surface area of a sphere?
That is correct because the surface area of a sphere is: 4*pi*radius squared
What is the surface area of a cylinder with 4m in diameter and 6m in height?
The surface area of a (closed) cylinder equals the surface area of both bases (the top and bottom), i.e. pi x radius squared (first base) + pi x radius squared (second base), plus the lateral surface area (the surface area of the curved side), i.e. circumference (pi x diameter) x height. Inserting the numbers: SA = pi x (2 m.) squared + pi x (2 m.) squared + pi x 4 m. x 6 m. = pi x 4 m. squared + pi x 4 m. squared + pi x 24 m. squared = 8 x pi m. squared + 24 x pi m. squared = 32 x pi meters squared.
What is the area of a 4' circle?
It is: pi*radius squared
Why is 4 pi r squared the surface area?
Because 4*pi*radius2 is surface area of a sphere
How does pi relate to the circumference and diameter of a cirle?
The cicumference of any circle divided by its diameter is aways equal to pi.
