Recall that the relationship between the circumference of a circle and its diameter is always the same ratio, 3.14159265, pi, or π. That number, π, times the square of the circle's radius gives you the area of the inside of the circle, in square units. Area of a circle formula. If you know the radius, r, in ...
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 WebThe formula to find the circumference when radius is given is Radius = Circumference/ (2*π) The formula to find the area when radius is given is Area of circle = π*Radius*Radius In the above formulas, π=3.14159 and R …
WebFeb 2, 2024 · Use the formulas to calculate the circumference and area: c = 2πr and A = πr². The circumference should equal c = 2π × 8 cm = 50.265 cm. The area should equal A = π × (8 cm)² = 201.06 cm². To check your results, input the 8 cm diameter in the calculator. The results should also be 50.265 cm and 201.06 cm².
