A circular swimming pool has a diameter of the 26 feet.

What is the area of the swimming pool?

Use 3.14 to approximate for π.

Enter your answer, as a decimal rounded to the nearest tenth, in the box.

___ ft2

A = 530.7 ft^2

Step-by-step explanation:

The diameter is 26 ft

The radius is 1/2 of the diameter

r =d/2 =26/2 = 13 ft

The area of the pool is

A = pi r^2

A = 3.14 (13)^2

A =530.66 ft^2

Round to the nearest tenth

A = 530.7 ft^2

The area is 530.7 ft^2

Step-by-step explanation:

Half the diameter is the radius.and we need to find the radius.

26/2 = 13

the area of a circle uses the formula   A= nr^2

A= 3.14 * 169

A= 530.66

Rounded to nearest tenth is  530.7

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
