Hello!
We know that the formula for area of a circle is:
A = pi × r^2
A semi circle is half of a circle, which means that its formula would be have of a circles as well.
Formula for area of a semi circle:
A = (pi × r^2) / 2
We'll use the same formula for a semi circle, only we'll divide it by 2 since it's a half circle.
A = (pi × r^2) / 2
A = (3.14 × r^2) / 2
A = 78.5 / 2
A = 39.25
ANSWER:
The area of the semi circle is C.) 39.25 centimetres squared.
C. f (0) = (0-8)(0+3), so (0, -24)
1 inch= 12 miles
Multiply 6 1/2 inches by total number of miles per 1 inch (12).
= 6 1/2 * 12
convert to improper fraction
= 13/2 * 12
multiply numerators
= (13*12)/2
multiply in parentheses
= 156/2
divide
= 78 miles
ANSWER: (A) 78 miles
Hope this helps! :)
