A semi circle is half a full circle. Find the area of the full circle and divide it by 2.
Area of a circle = pi x r ^2
R is half the diameter
Area of full circle:
Area = 22/7 x 21^2
Area = 1386 sq. Ft
Area of stage = 1386/2 = 693 square feet
Answer:
x=55
Step-by-step explanation:
90 degree angle
90-35=55
Since f and g are parallel to eachother, the sum of the angle 7x and 2x+36 would equal 180. To solve for x, you add 7x+2x+36, set it equal to 180, and then solve for x.
x= 16
