Ray df or ray fd because both of these letters are consecutive in both of the angles.
Answer:
6,861 cm³
Step-by-step explanation:
First, find the volume of of the cylinder, the formula fr a cylinder is π·r²·h
π·9²·15≈3,817
Then, find the volume of the cone, 1/3(πr²)(h)
π·9²·12≈3,054
Finally, add them together to get ≈6,861 cm³
Answer:
supplement of an angle is what must be added to that angle to get 180
51+supplement=180
minus 51 both sides
supplement=129
answer is 129
