About 530.93 inches2
A circle with a radius of 13 units has an area of 530.93 square units.
A = 530.9
To find the area of a circle with a radius of 13 km, you use the formula for the area of a circle, A = πr², where r is the radius. In this case, A = π(13 km)² = π(169 km²) ≈ 530.14 km². Therefore, the area of the circle is approximately 530.14 square kilometers.
radius of a circle = 13 metersArea of a circle =π * radius2radius = square root of Area/π=√531/π=√ 531/3.1416=√ 169= 13
The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the radius is 13, we can substitute this value into the formula: A = π(13)^2. Calculating this, we get A = 169π, which is approximately 530.93 square units.
