How do you find diameter of a circle with the diameter 10?
You have answered this question for yourself; the answer is '10' Do you mean to ask ; What is the circumference/area of a circle, with a diameter of '10'?. If so , commit to memory ' elementary school maths. A = pi r^2 C = 2 pi r or pi d . From this 2r = d Hence 2r = 10 r = 5 C = 10 pi = 31.41592.... units A = pi 5^2 = 25 pi = 78.5398... units^2
What is the area of a circle with a diameter of 8?
Commit to memory A = pi r^2 C = 2 pi r or pi d NB 2r = d This is elementary school maths. Hence if d = 2r 8 , then r = 8/2 = 4 Hence A = pi 4^2 A = 16 pi pi is a constant at 3.141592.... A = 16*3.41592.... = 50.26554.... units^2
What is the probability that a randomly thrown dart hits a blue or yellow region given that it hits the square board?
To determine the probability that a randomly thrown dart hits a blue or yellow region on a square board, you need to know the areas of the blue and yellow regions in relation to the total area of the square board. The probability can be calculated by dividing the combined area of the blue and yellow regions by the total area of the board. If the areas are not specified, you cannot provide a numerical probability. Therefore, the probability is given by the formula: P(blue or yellow) = (Area of blue + Area of yellow) / (Area of the square board).
How do 1 Solve for quartiles in a grouped data?
formula in solving quartiles: QK = ([kN - <CF] / FQK)i where in: Q = Quartile k = given value N = Total number of variables <CF = Lower Frequency of Lower Area i = Interval
What is the formula for finding diameter when given the area?
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
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
Which area is bigger a circle with a diameter of 10 feet or a triangle with an area of 100 sq ft?
Use the standard formula to calculate the area of the circle, then you can compare with the area given for the triangle. Note 1: The formula for a circle is: area = pi x radius squared Note 2: The radius is half the diameter
What is the diameter of a circle if the area is 56?
To find the diameter of a circle when given the area, we first need to calculate the radius. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the area is 56, we can rearrange the formula to solve for the radius: r = √(A/π) = √(56/π) ≈ 4.74. Finally, to find the diameter, we double the radius, so the diameter of the circle is approximately 9.48 units.
What is the area The diameter of a circle is 8 feet.?
The area of a circle can be found using the formula A = πr^2, where r is the radius of the circle. Since the diameter is given as 8 feet, the radius would be half of the diameter, which is 4 feet. Plugging this into the formula, the area of the circle is approximately 50.27 square feet.
How do you work out the area of a circle in a square?

What is the formula for area of the circle?
The formula for area of a circle is TTr2.This means that we multiply 3.14(the rounded off nunber for pi) by the radius and radius(3.14xradiusxradius).If the diameter is given,divide it by 2 to get the radius.
Find the diameter of a circle whose area is 78.5cm2?
The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. We can solve for the radius by rearranging the formula: r = √(A/π) Given that the area is 78.5cm^2, we can substitute this value into the formula: r = √(78.5/π) ≈ 5.01cm Finally, we can calculate the diameter by doubling the radius: d = 2r ≈ 10.02cm Therefore, the diameter of the circle with an area of 78.5cm^2 is approximately 10.02cm.
What is theRelationship between the diameter of a circle and the area of the same circle?
The area of a circle is given by the formula pi*r^2, where r is the radius of the circle. Diameter = 2*r, so: area = pi*(d/2)^2 = (1/4)*pi*d^2
How do you figure the area of a circle if you know the diameter?
The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.
What is the formula for the area of a circle with a diameter?
The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
What is the diameter of a circle whose area is 314 cm square?
To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 cm.
