How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
How do you find the area of a circle if the diameter is given?
multiple the diameter by 2 to get the radius, then use your equation and go from there
How do you find the area of a circle when given diameter?
A = pi x d2 / 4
How do you find diameter of a circle if area is given?
A=(pi)r2 d=2r Divide the given area by pi(3.14) and take the square root. This is the radius so multiply by 2 to get the diameter.
How do you find the diameter when given the area?
depends greatly on the thing you are working with. assuming a circle with area A the diameter is 2*sqrt(A*pi) since A =r*r*pi and diameter=2*r
How do you find the diameter of a cylinder when the lateral area is given?
Given only the lateral area, you cannot determine the diameter.
What is the most easy way to find the area?
It depends on the shape of the area you need to calculate. There are formulae for given shapes but not necessarily for irregular ones
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
How do you find the surface area of a cylinder when given the diameter?
half the diameter and then get the radius times pi and square it
How do you find the area of a circle if the diameter is given?
multiple the diameter by 2 to get the radius, then use your equation and go from there
If the area of a circle is given as 67cm squared find the diameter and then circumference of this circle?
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
How do you find the area of the circle if diameter is given?
Area = pi*r2 where r is the radius. Since r = diameter/2, then area = pi*d2/4
How do you find the area of a circle when given diameter?
A = pi x d2 / 4
How do you find diameter of a circle if area is given?
A=(pi)r2 d=2r Divide the given area by pi(3.14) and take the square root. This is the radius so multiply by 2 to get the diameter.
What is the formula to find the area of a circle with with a diameter?
if you are given a diameter divide it by two to get the radius! From then on, it is just simple Pi R Squared
How do you find the diameter when given the area?
depends greatly on the thing you are working with. assuming a circle with area A the diameter is 2*sqrt(A*pi) since A =r*r*pi and diameter=2*r
How would you find the area of a circle if you're given the diameter?
divide the diameter by 2 and square the number you just got and then multiply it by pi
