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.
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
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).
A square has sides of length 8.2 centimeters. What is the perimeter?
NO. A square has 4 equal sides with the sides perpendicular each other. A circle has infinite sides.
The sides of the Square.
25 square centimeters.
324 square centimeters.
No, because the two lowest sides have equal more than the largest when added.
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
If the area of a square is 49 square centimeters, the length of each of its sides are: 7 cm.
