Answer:

121°

Step-by-step explanation:

The sum of the angles of a triangle is 180°.

(x)° +(x -5)° +(3x +25)° = 180°

5x +20 = 180 . . . . . . . . . . . . . . collect terms, divide by °

5x = 160 . . . . . . . . . . . . subtract 20

x = 32 . . . . . . . . . divide by 5

Angle G is ...

∠G = (3x +25)° = (3·32 +25)°

∠G = 121°

cylinder has a height of 7 feet. Its volume is 1,406.72 cubic feet. What is the radius of the cylinder?

horsena [70]

Answer:

8 feet.

Step-by-step explanation:

The formula for volume of a cylinder is $r^{2} \pi h$ (using 3.14 for $\pi$ ). So it would be $r^{2}$ times 7 times 3.14 which equals $r^{2}$ times 21.98. 1406.72 divided by 21.98 is 64. The square root of 64 is 8. The radius is 8.
