Chapter 1: Q19. (page 25)

Short Answer

Expert verified

The perimeter of the given figure is 10.3 ft.

Step by step solution

01

Step 1. Given information.

In the figure, the diameter of the semi-circle is 4 feet and the perimeter is given by the circumference of the semi-circle.

02

Step 2. Concept used.

Circumference of a semi-circle with diameter d is given by C=πd2.

03

Step 3. Calculations.

The circumference of a circle is

C=3.14×42=3.14×2=6.28feet

Here, the perimeter of the given figure is equal to the sum of the circumference and diameter of the semi-circle.

P=6.28+4=10.28feet

Rounding off to the nearest tenth, we get,

P=10.3feet

Thus, the perimeter of the figure is 10.3 feet.
