How do you find the circumference of a cicle?
To find circumference you must multiply twice the radius by π, or using the diameter, if it gives it to you, multiply that by π.
How do you find the surface area of a circle?
you find the surface area of a circle by first finding the area of the circles/ two ends. you do this by multiplying the diameter by pi then multiply by two, that is both ends put together then you find the area of the flat part by finding out the circumference of the circle ends, then multiply that by the height of the cylinder. circumference= pi times the diameter then add all your calculation together, and you have the surface area of your cylinder :)
How do you find circumference with given diameter?
If you only have a given diameter you have to multiply the diameter by Pi (3.142) or 3.14 and then you get the circumference!
How do you find the area of a square and a rectangle?
Multiply the length and width to find the area of both a rectangle and square.
How do you find the circumference of a pipe?
Measure the inside diameter and multiply it by 3.14159 (pi)
How do you find the length of a rectangle around a cylinder?
find the circumference of the circle and multiply it by the height of the cylinder
How do you find the length of perimeter or circumference of a circle?
Since pi is the ratio of a circle's circumference to its diameter, multiply the diameter by pi (about 3.14159) to get the circumference.
What is the arc length if the length of the arc is 95 degrees?
Find the circumference of the whole circle and then multiply that length by 95/360.
How do you find the circumference of a circle using the length of the diameter?
Multiply the diameter by the constant pi.
How do you figure out the surface area of a cylninder?
Find the circumference of the circles (the ends) and multiply it by the height of the cylinder. Then add that to the area of the ends.
How do you find the diameter of a circle if you have the circumference?
C=2(3.14)rThis is circumference equation for circles. If you have the circumference, you need to input it into the equation and solve for r. r is the radius of the circle, so to determine the diameter, which is 2 times the length of the radius, you just need to multiply the number you got for r times 2.
How do you find the circumference of circles?
The circumference of a circle = pi*diametre = 2pi*radius
Calculate the circumference of a circle with each diameter?
Multiply each of the diameters by pi (pi = 3.14159265 or 3.14 for rough approximation) to find the circumferences of the circles.
What are the steps of finding the circumfrerence?
This is the equation for the circumference... C= 2 x r x pi r = the length of the radius pi = 3.14159 To find to circumference just find the radius of your cricle that you want to find the circumference of. then simply multiply 2 and 3.14159 by the radius and your circumference is the answer
How do you find the circumference of a cicle?
To find circumference you must multiply twice the radius by π, or using the diameter, if it gives it to you, multiply that by π.
How is pi used to find circumference of circles?
Pi times the diameter of a circle gives its circumference.
Can you find the area of a square if you have the circumference?
Circumfrences are only for circles.
