WebAug 2, 2024 · If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter. This goes back to manipulating the formula for finding the area of a circle, A = πr 2, to get the diameter. You can transform this into r = √ (A/π) cm. [3] Example WebArea of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2, (Pi r-squared) where r is the radius of the …

WebThe equation of a circle is π r 2, traditionally in school we have always left the answer in terms of pi (i.e.) if the radius r = 2 then the area A = 4 π. If one were to attempt to write the area of a circle in decimal form (i.e.) if the radius=2 then the area A = 4 π, but π doesn't have an end, it has (per what I have learned in school) an ... WebApr 7, 2024 · The circumference of a circle is the linear distance around the circle, or the length of the circle if it were opened up and turned into a straight line.. The area of a circle is the number of square units it takes to fill up the inside of the circle.. Note the circumference and area apply to the entire circle..

Answered: Find the area of the circle. Leave your… bartleby
WebThis is the reasoning: A circle has an angle of 2 π and an Area of: πr2. A Sector has an angle of θ instead of 2 π so its Area is : θ 2π × πr2. Which can be simplified to: θ 2 × r2. Area of Sector = θ 2 × r 2 (when θ is in radians) Area of Sector = … WebApr 1, 2024 · Example: find the area of a circle. Task 1: Given the radius of a circle, find its area. For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in.. Task … WebSep 15, 2024 · As with arc length, we have to make sure that the angle is measured in radians or else the answer will be way off. So converting θ = 117 ∘ to radians and using r = 3.5 in Equation 4.3.1 for the area A of the sector, we get. θ = 117 ∘ = π 180 ⋅ 117 = 2.042 rad ⇒ A = 1 2 r2 θ = 1 2 (3.5)2 (2.042) = 12.51 m2 .
