WebSolution: Estimate 3 × 8 2 = 3 × 64 = 192. The area of the circle, A = π r 2. = 22 7 × 8 2 (Substitute 22 7 for π and 8 for ‘r’) = 22 7 × 64 (Evaluate 8 2 and divide out the common factor) = 201.14 (Multiply) The area is about 201 square centimeters. It’s reasonable compared to the estimated value of 192 ∼ 201.14. WebA circle is a curved shape and its area and perimeter are given by its radius. Area of circle is πr2 Perimeter or circumference of circle is 2πr. What is the perimeter and area example? If a square has side length of 2cm then, Area of square = side2 = 22 = 4cm2 Perimeter of square = sum of all sides = 2+2+2+2 = 8
WebArea of a circle can be calculated by using the formulas: Area = π × r 2, where 'r' is the radius. Area = (π/4) × d 2, where 'd' is the diameter. Area = C 2 /4π, where 'C' is the circumference (sometimes referred to as perimeter).
