The radius of the circle is 7 cm and finds its circumference and area.

To find the circumference and area of a circle with a radius of 7 cm, you can use the following formulas:

Circumference (C) of a circle:
C = 2πr

Area (A) of a circle:
A = πr^2

Where:

π (pi) is approximately equal to 3.14159.
r is the radius of the circle.
Now, let's calculate:

Circumference:
C = 2π * 7 cm
C ≈ 2 * 3.14159 * 7 cm
C ≈ 43.982 cm (rounded to three decimal places)
So, the circumference of the circle with a radius of 7 cm is approximately 43.982 cm.

Area:
A = π * (7 cm)^2
A ≈ 3.14159 * 49 cm^2
A ≈ 153.937 cm^2 (rounded to three decimal places)
The area of the circle with a radius of 7 cm is approximately 153.937 square centimeters.
