The question is in the photo, that answer is not correct. At least I do not know if it is.

Step-by-step explanation:

To get the solution lying in the shaded region,

Justify the equation with the given options,

Option (1)

For (1, 1),

True.

Therefore, point (1, 1) justifies the equation.

Option (2)

For (4, 1),

False.

Therefore, point (4, 1) doesn't justify the equation.

Option (3)

For (-1, 2),

False.

Therefore, point (-1, 2) doesn't justify the equation.

Option (4)

For (2, -2),

False.

Therefore, point (2, -2) doesn't justify the equation.

Option (1) will be the answer.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
