I need help I'm failing in class I need to find a inscribed angle but it's hard.

Step-by-step explanation:

The equation to use is: angle DEF = 1/2(arc FGD),

so (8x-11) = 1/2(4x+26)

8x-11 = 2x+13

6x = 24

x = 4

angle DEF = 21 degrees

arc FGD = 42 degrees

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

345
