The answer would be . Y=7 1/2x. You can find this buy finding the slope method. Which is y2-y1/x2-x1
The answer would be 9! 3 x 9 = 27.
Answer:
C≈40.84
Step-by-step explanation:
C = 2πR
Consider the cross-sectional right triangle shown in the figure.
One of its sides is the height of the pyramid, with length H. The other side is half of the square base, so its length is 81 m. The hypotenuse of this triangle is the height of one of the faces.
By right triangle trigonometry,

,
thus,

.
Answer: C) 52 m
