Answer:
x = 30
Step-by-step explanation:
90 + 4x + 5x = ( sum of full angle is 360)
90 + 9x = 360
transpose
9x = 360 - 90 = 270
x = 270 ÷ 9
x = 30
Area of a rectangle is found with the formula
A = Length x width
For your problem...
A = 4.325 x 3.6
A= 15.57 meters^2

Answer
+ =25
Step-by-step explanation:
the standard eqn of circle can be find as
(x-g)^2 + (y-h)^2=r^2
A. To find the area of a circle you need to use the formula A= π r²
The radius (R) is half of the diameter . . . that's 6.5 cm .
r² = (
6.5)² = 42.25 cm²
Area = π r² = 42.25 π = <em>132.7 cm²</em>
B. Area of a rectangle is just (length) x (width).
Length = 12 cm
Width = 5 cm
Area = (12 cm) x (5 cm) = <em>60 cm²</em>
C. The shaded portion is the part of the circle that's NOT in the rectangle. So its area is (area of the circle) - (area of the rectangle)
Area = (132.7 cm²) - (60 cm²) = <em>72.7 cm²</em>
