What is the radius of a circle with an area of 345 square centimeters?
10.48cm
What is the radius of a circle whose area is 1256 square centimeters?
To find the radius of a circle given its area, you can use the formula A = πr^2, where A is the area and r is the radius. In this case, the area is 1256 square centimeters. So, 1256 = πr^2. To solve for r, divide both sides by π and then take the square root. Therefore, the radius of the circle is approximately 20 centimeters.
What is the surface area in square centimeters of a hemisphere that has a radius of 14 centimeters?
Total surface area = 1847.26 sq cm.
Find the area of a circle with a radius of 4.6 centimeters?
Oh, what a happy little question! To find the area of a circle, we use the formula A = πr^2. With a radius of 4.6 centimeters, we simply plug that into the formula: A = π(4.6)^2. After a little calculation, we find the area to be approximately 66.45 square centimeters. Just like that, we've created a beautiful area calculation together!
