12 cze 2024 · A = \pi (5)^2. Calculate the square of the radius: A = \pi \times 25. Now, multiply by (\pi): A \approx 3.14159 \times 25 \approx 78.54 \text { square units} Therefore, the area of a circle with a radius of 5 units is approximately 78.54 square units.
8 cze 2024 · The area of a circle is determined by the formula: \ [ \text {Area} = \pi r^ {2} \] where \ (r\) is the radius of the circle and \ (\pi\) (approximately 3.14159) is the constant representing the ratio of the circumference of any circle to its diameter. Example Calculation. For a circle with a radius of 12.5 units:
1 dzień temu · The area of a corner or segment of a circle can be calculated using the formula: \ [ S = (1 - \frac {\pi} {4})r^2 \] where: \ (S\) is the area of the corner, \ (r\) is the radius of the circle.
12 cze 2024 · Q.5) How do you calculate the area of a circle? Ans) The area of a circle can be calculated using the formula: A = πr², where A represents the area enclosed by the circle, and r is the radius of the circle.
