Answer
what is the formula for the area of a rectangle

A: a = length + width

B: a = 2(length + width)

C: a = length^2 + width^2

D: a length * width

Answer

To find the circumference of a circle, you use the formula: C = 2 * π * r, where r is the radius of the circle.

Let's say the radius of the circle is 5 units.

C = 2 * 3.14 * 5
C = 31.4

Therefore, the circumference of the circle is 31.4 units.

To find the circumference of a circle, you use the formula: C = 2 * π * r, where r is the radius of the circle.

Given that the radius (r) is 12 cm:

C = 2 * 3.14 * 12
C = 75.36

Rounded to the nearest tenth, the circumference of the circle with a radius of 12 cm is 75.4 cm.

To find the area of a circle, you use the formula: A = π * r^2, where r is the radius of the circle.

Given that the radius (r) is 12 cm:

A = 3.14 * (12)^2
A = 3.14 * 144
A = 452.16

Rounded to the nearest tenth, the area of the circle with a radius of 12 cm is 452.2 square cm.

To find the perimeter of a rectangle, you add up all its side lengths.

Given that the length of the rectangle is 8 units and the width is 5 units:

Perimeter = 2(length) + 2(width)
Perimeter = 2(8) + 2(5)
Perimeter = 16 + 10
Perimeter = 26

Therefore, the perimeter of the rectangle is 26 units.
