If a cone has the same radius and height as a cylinder, the volume of the cone is A)one- fourth,
B)one-third, C)half or D) two-thirds the volume of the. If a cylinder and sphere have the same radius and the cylinder's height is twice its radius, then the volume of the sphere is A)one-fourth, B)one-third, C)half or D)two-thirds the volume of the cylinder.

all it means is function 3

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
