Answer:
3053.63 in^3
Step-by-step explanation:
The equation for the volume of a sphere is
The radius of the sphere is given to us as 9 inches.
Multiply 1/4 (4r -12) = r-2
r-3 = r-2
Subtract r from each side
-3= -2 this equation has no solution
Answer:
1)
2) area of the shaded region

67π/8 feet
Answer:
x = 8.3
y = 20.3
Step-by-step explanation:
or
or
Angle AEB and Angle DEC are opposite angles which means they are equal in measure. Hence,
⇛ Angle AEB = Angle DEC
⇛ 9x + 8° = 3x + 42°
⇛ 9x - 3x = 42° - 8°
⇛ 6x = 34°
⇛ x = (34/6)°
<u>To </u><u>find</u><u>:</u> Angle DEC = 3(
34/6 °) + 42° = <u>5</u><u>9</u><u>°</u><u> </u><u>(</u><u>Ans)</u>
