In the figure below, one side of the right triangle is a diameter of the semicircle.
olga55 [171]

Answer:

Option (A)

Step-by-step explanation:

One side of the given triangle is a diameter of the semicircle given.

Measure of the diameter = 10 units

Total area of the semicircle = \frac{1}{2}\pi (r^{2})

                                              = \frac{1}{2}\pi (5)^2

                                              = 39.27 square units

Area of the right triangle = \frac{1}{2}(\text{Base})(\text{Height})

                                         = \frac{1}{2}(6)(8)

                                         = 24 square units

Area of the shaded region = Area of the semicircle - Area of the right triangle

                                            = 39.27 - 24

                                            = 15.27 square units

                                            ≈ 15 square units

Therefore, option (A) will be the answer.

Ken's landscape gardening business creates odd-shaped lawns that include semicircles. Find the area of this semicircular section
salantis [7]

Answer:

Area of semicircular lawn is 9.82 square meter.

Step-by-step explanation:

Given:

Diameter of the semicircle = 5 m

So we will find the radius.

Radius is half of the diameter.

Radius r=\frac{5}{2}=2.5\ m

We need to find the area of the lawn.

Solution:

Now we know that;

Area of semicircle is half times π times square of the radius.

framing in equation form we get;

Area of semicircular lawn = \frac12\pi r^2=\frac12\times\frac{22}{7}\times 2.5\times 2.5=9.82\ m^2

Hence Area of semicircular lawn is 9.82 square meter.
