What times what equals 314?
1 x 314 and 2 x 157
What is 314 divided by 2?
0.6369
What is 2 pi over 2?
2 pi / 2 = pi.
What is the area of a circle when the diameter is known?
let d be the diameter of the circe. So the radius is d/2 or half the diameter by definition. The area of the circle is Pi x r^2 so it is Pi (d/2)^2 this is (Pix d^2)/4 SO the area is Pi times the diameter squared all divided by 4
Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
What is the area of a circle with the circumference of 62.8 inches?
Circumference = 2 pi r = 62.8 so r = 31.4/pi = 10 Area = pi r2 = 100 pi = 314 in2
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 surface area of a sphere with a radius of 5?
It is: 4*pi*52 = 314.159 square cm to three decimal places
What is he definition of area?
area = pi * radius* 2
What is the area of a circle with a radius of 10 in using 3.14 for pi?
Using 3.14 as Pi the area of circle is: 314.0
How do you get the circumference out of the area?
you divide by pi (3.14) then take the square root, then multiply by 2 and multiply by pi (3.14)...in that order i.e. if you have a circle with area of 314 square inches, you take the 314 and divide by 3.14...you get 100...then you take the square root of 100...you get 10...then you multiply by 2...you get 20...then you multply by 3.14...you get 62.8 inches...thats the circumference of a circle with an area of 314 square inches
What is the circumference of a circle with an area of 314 in2?
Tells you the answer is 2*sqrt(314*pi) inches, which is approximately 62.82 inches Seriously though. Use metric units in maths it makes everything just work!
How do you dind the area of a circle if you have the circumference?
C=2*pi*r A=pi*r^2 so you divide the circumference by 2*pi (~6.28), then square that and multiply by pi (~3.14) and that would get you the area of a circle i.e. if Circumference = 62.8 inches...you divide by 6.28 and get 10, then you square that (10*10=100), then you multiply by pi...100*3.14= 314 square inches.
What is the radius and circumference of a sphere when its surface area covers 314 square inches taking pi as 3.14 and showing your work?
S.A. = 4 pi r^2 Substituting 314 = 43.14r^2 Algebraically rearrange 100/4] r^2 = 314 / (4 * 3.14) r = sqrt[314/(4*3.14)] r = sqrt[ 100/4] r = sqrt[25] r = 5 inches The circumference of a sphere is a circle. Hence C = 2 pi r C = 23.145 C = 10*3.14 C = 31.4 inches.
If the radius is 10 then what is the circumference and area?
Assuming you are talking about the circle, and pi equalling 3.14. Circumference = 2.pi.r =2x3.14x10 = 62.8 Area = pi r2 = 3.14 x 10 x 10 = 314
What are the factors and prime factors of 314?
The positive integer factors of 314 are: 1, 2, 157, 314 The prime factors of 314 are: 2, 157
How many times can 2 can go into 314?
314 ÷ 2 = 157
