Question

The diagram shows a semicircle carpet with a
diameter of 7ft. What is the area of carpet? Use
pi = 22/7​

Answer 1

Answer:

Area of carpet = 18.25 sq. ft.

Step-by-step explanation:

Diameter = 7 ft

Radius = 1/2 of diameter

Radius = 1/2 × 7 ft

Radius = 3.5 ft

Area of semicircle = 1/2 (¶r²)

= 1/2 [ 22/7 × (3.5)²

= 1/2 [ 22/7 × 12.25 ]

= 1/2 [ 22 × 1.75 ]

= 1/2 × 38.5

= 19.25 sq. ft .

Answer 2

Given:

the diameter of the semi-circle carpet is 7ft

To Find:

Area of the carpet

Solution:

  Diameter = 7ft

  Radius = 1/2 of diameter

               = 1/2 of 7ft

               = 3.5 ft

 Area of semicircle carpet = 1/2πr²

                                            = 1/2× 22/7× (3.5)²

                                            = 1/2[22/7 × 12.25]

                                            = 1/2[22× 1.75]

                                            = 1/2 × 38.5

                                            = 19.25²ft

Therefore, the area of the carpet = 19.25²ft
