How do you multiply two times pi times two?
2 x pi x 2 = 4 x pi
What is the circumference of a circle with a diameter of four feet?
Circumference equals pi (which is about 3.14) times diameter (or pi times 2 times the radius, which is the same thing). Pi times 4' = 12' 6.8"
What is the circumference of a 4 in diameter?
Circumference of circle: 4 times pi in inches
What is the area of circles with a radius of 4 inches and with a diameter of 4 inches and with a circumference of 4 inches?
The area (A) of a circle is pi (about 3.14) times the square of the radius (r). The circumference (c) of a circle is pi times its diameter (d), or pi times twice its radius. Knowing that, we can investigate the three circles. If rcircle = 4, Areacircle = pi r2 = 3.14 x 42 = 3.14 x 16 = 50.27 sq. in. If dcircle = 4, Areacircle = pi (d/2)2 = 3.14 x (4/2)2 = 3.14 x (2)2 = 3.14 x 22 = 3.14 x 4 = 12.57 sq. in. If c - 4, Areacircle = pi (c/2 pi)2 = pi (42/4 pi2) = pi x 16/ 4 x pi2 = 16/ 4 x pi = 4/3.14 = 1.27 sq. in.
What is the volume of this shere that has a radius of 6 inches?
Volume of sphere: 4/3 times pi times 6 cubed = 288*pi cubic inches
What is 4 times pi times pi times 4 divided by 2?
4 times pi times 4 divided by 2 is 78.9568352087
What is 4 times pi times 6 to second power?
you said 4 pi times 6 to the second power.thats 452.38934236
How do you multiply two times pi times two?
2 x pi x 2 = 4 x pi
What is pi times 4 times 4.8?
3.141592653589793 * 4 * 4.8 = 60.31858
What is pi times 3 divided by 4?
12
What is the cotangent of 7 times Pi divided by 4?
28
What is the circumference of a circle with a diameter of four feet?
Circumference equals pi (which is about 3.14) times diameter (or pi times 2 times the radius, which is the same thing). Pi times 4' = 12' 6.8"
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
Fine the volume of a sphere?
Volume of a Sphere. Volume= (4/3)(pi)r^3 Multiple 4/3 times pi times the radius to the third power. The surface area of a Sphere is 4(pi)r^2
Surface area of a sphere?
4 times Pi times radius times radius
What an equation which expresses circumference if the radius is 4 centimeters?
2 times 4 times pi (3.14)
Find the the surface area of a sphere with a radious of 6?
Surface area of a sphere equals 4 times Pi times the Square of its radius. So plugging in the needed radius of 6 makes the formula Area=4*pi*R^2 or 4*pi *6^2 or 4*36*pi and with pi=3.141592654... this becomes 452.3893421... units (144*3.141592654...)
