The diameter of the circle is 5.4 cm. The shaded area is 180 degrees, which is 1/2 of the circle.
Calculate the area of the full circle and divide by 2.
Area = PI x r^2
r = 5.4/2 = 2.7
Area = 3.14 x 2.7^2 = 22.90
Area of shaded part: 22.90 / 2 = 11.45 cm^2.
The answer is A.

Answer:
254
Step-by-step explanation:
first find the diameter of the big circle by adding the 2 founded numbers
which is 18
then the Radius = 9
to find area,

which is

Answer:157/10
Step-by-step explanation:
Make 15 into an improper fraction (every number is a fraction over 1) so multiply the numerator(15) and the denominator(1) by 10 to get 150/10 then add 150/10 to 7/10 to get 157/10
Yes if you could help that would be so nice!!!!
