Answer: 103.25

Explanation:

area of the rectangle is 4*16= 64

The area of the complete circle is
\pi r^(2)

r=d/2

r=10/2

r=5


25\pi is the area of the full circle


(25\pi )/(2) is the area of the semi- circle

area of the figure


64+(25\pi )/(2)=103.27

Answer:

B) 103.25

Explanation:

Area of rectangle:

A = bh

A = (16)(4)

A = 64

Area of a semi-circle:

r = d/2 = 5

A = (πr²)/2

A = (3.14 * 5²)/2

A = (3.14 * 25)/2

A = (78.5)/2

A = 39.25

Combined:

64 + 39.25 = 103.25
