Answer:
1 is 8x + 16 = 6x
Step-by-step explanation:
Area of circle = Pi x r*2
If diameter is 18, radius is 9.
Area = pi (3.14) x r*2 (9*2 = 81) .. 3.14 x 81 = 254.34 sq cen = total area of circle.
A circle is 360 degrees, the shaded area is 270 degrees. the shaded area is 3/4 (270/360) of the area of the circle.
254.34 x 3/4 = 190.755 sq cen
Hope this helps
Answer:
65 = 6x + 7
6x = 58
x = 9.6666666...
65 + y + 9 = 180
y = 106
Step-by-step explanation:
Cosα=x/L
x=Lcosα, we are told the ladder is 10ft and α=42.5 so
x=10cos42.5° ft
x≈7.37 ft (to nearest hundredth of a foot)
