Answer:
76.93 units²
Step-by-step explanation:
Diameter, = 14
radius = 1/2 x diameter = 7
Area of circle = π r²
Area of semi-circle = 1/2 x area of circle = (1/2)π r²
given r = 7 and π = 3.14
Area if semicircle,
= (1/2)π r²
= (1/2)(3.14) (7)²
= 76.93 units²
to find the area of a regular circle you have to square the radius which is half of the diameter. so I would assume you would find the area of the circle as if it were a full circle and then half that number to get the area of the semi circle. so going off of that the area would be 24.5
