please help! thanks i really need help last quesiton

Answer:
79.625
Step-by-step explanation:
The area of a semicircle is half of the area of the circle. As the area of a circle is πr2. So, the area of a semicircle is 1/2(πr2 ), where r is the radius. The value of π is 3.14 or 22/7. The area of a rectangle is Length x Width. 5 is the diameter of the circle, and the radius is half of that
5 x 12 = 60
A = nr^2 =
A =3.14 x R^2 =
R = 5/2 = 2.5
R = 2.5
A = 3.14 x 2.5[tex]^{2}[/tex]
A = 3.14 x 6.25
A = 19.625
60 + 19.625
79.625
Answer:
79.625
Step-by-step explanation:
5x 12 = 60A = nr^2 =A =3.14 x R^2 =R = 5/2 = 2.5R = 2.5A = 3.14 x 2.5A = 3.14 x 6.25 A = 19.62560 + 19.625
79.625
