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
How do you multiply two times pi times two?
2 x pi x 2 = 4 x pi
How do you find the circumference of a circle with a radius of 3.5?
Two times the radius times pi equals the circumference of a circle. 2 x 3.5 = 7 7 x pi = 7 x 3.1416 = 21.99 or about 22
If f x equals sin2 x then f pi over 2 equals?
it equals 1
What is the formula to calculate the square footage of a circle?
The area of a circle equals pi (3.1415926...) times the radius squared, or pi(r2). So if the distance from the center of the circle to the edge is 2 feet, you would multiply 2 by 2, and then multiply that result by pi, giving an answer of 12.6 square feet (assuming you rounded pi off to 2 decimal places).pi x radius x radius equals the area of a circle .
Area of a circle with a radius of 12?

How do you multiply two times pi times two?
2 x pi x 2 = 4 x pi
What is the Surface Area of a cylinder with diameter of 12 cm and a height of 20 cm?
(12 x "pi" x 20) + 2(36 x "pi") which equals 314 x "pi" which equals about 985.96 when pi is 3.14
What is the volume of a cylinder with a height of 5 and radius of 2?
The volume of a cylinder equals the area of the base times the height, which equals pi x radius squared x height. Inserting the numbers, V = pi x (2 m.) squared x 5 m. = pi x 4 m. squared x 5 m. = 20 x pi meters cubed or 20 x pi cubic meters.
How do you find the circumference of a circle with a radius of 3.5?
Two times the radius times pi equals the circumference of a circle. 2 x 3.5 = 7 7 x pi = 7 x 3.1416 = 21.99 or about 22
What is the diameter of a circle if the circumference is 7?
divide dy pi. the rule is diiameter (or 2 radius) multiplied by pi equals circumference so: 2 pi x radius= circ and, since diameter is 2 times the radius, pi x D= circ
If f x equals sin2 x then f pi over 2 equals?
it equals 1
If you double the radius of a circle what happens to the area?
If you double the original radius, the area will become 4 times what it was. The area of a circle is pi*r^2 = A. If our new radius (lets say x) is double (x=2r), we have pi*x^2 = pi*(2r)^2, which equals 4*pi*r^2 = 4A, or 4 times the original area.
What is pi times 13?
Pi sorta equals 3.143.14 x 1340.82 (Approximate, but not by much)
What is the equation of the line tangent to the curve y equals cos x at the point x equals pi over 6?
y = 2(x) - (pi/3) + (sqrt(3)/2)
The radius of a circle is x plus 4 what is the circumference?
Circumference = (2) x (pi) x (Radius)= (2 pi) times (X + 4)= same as (2 pi X) + (8 pi)= same as [ pi (2X + 8) ]
What is the formula for finding the circumference of a circle?
The formula for the circumference of a circle is 2πr, or πd.C = pi x d (pi x diameter)or:C = 2 x pi x r (2 times pi times radius)(Pi or π is approximately 3.1416)
