Question

A circle has a diameter of 26 units. What is the area of the circle to the nearest hundred of a square unit?

Answer 1

Answer: The area is 530 square units

Step-by-step explanation: The diameter of the circle has been given as 26. That makes the radius 13, that is;

Radius = diameter/2

Radius = 26/2

Radius = 13

The area of a circle is derived by the formula;

Area = pi x r^2

Where pi is 3.14 and r is 13,

Area = (3.14) x 13^2

Area = 3.14 x 169

Area = 530.66

Approximately to the nearest hundred of a square unit,

The area of the circle is 530 square units

Answer 2

Answer:

531 square units

Step-by-step explanation:

Area of a circle = pi r2

Given

Diameter = 26 units

Radius r = diameter/2 = 26/2

= 13units

Pi = 3.14

Therefore

Area = 3.14 x (13)^2

= 3.14 x 13 x 13

= 530.66

= 531 square units
