π × (16.25cm)2
= 264.0625π cm2
≈ 829.5761cm2
16.25 cm will be the radius of the circle (32.5 divided by 2) Area of a circle = pi*radius2 = pi*16.252 = 51.05088062 square centimetres So the answer is 51 square metres correct to two significant figures.
The sides of the Square.
25 square centimeters.
324 square centimeters.
To find the length of the sides of a square given its area, you take the square root of the area. In this case, the area is 25 square centimeters. The square root of 25 is 5, so each side of the square is 5 centimeters long.
16.25 cm will be the radius of the circle (32.5 divided by 2) Area of a circle = pi*radius2 = pi*16.252 = 51.05088062 square centimetres So the answer is 51 square metres correct to two significant figures.
Largest area = pi*182 = 1017.876 square cm to 3 dp
pi*r2 = 28.26 Divide both sides by pi: r2 = 8.995437384 Square root both sides: radius = 2.999239468 diameter = 2*radius: diameter = 5.998478935 or 6 centimeters to the nearest cm.
The diameter length of the circle would be the same as the side length of the square. If a is the side of the square, then the radius is a/2, and the area of the circle would be (1/4)(pi)(a^2).
The sides of the Square.
NO. A square has 4 equal sides with the sides perpendicular each other. A circle has infinite sides.
It would be 32.8 centimeters. A square has 4 sides and equal sides. So 8.2 x 4 equals 32.8
25 square centimeters.
324 square centimeters.
No, because the two lowest sides have equal more than the largest when added.
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.
pi*radius2 = 169*pi Divide both sides by pi then square root both sides to find the radius: radius = 13 and 2*13 = a diameter of 26 cm
