Answer:
48 cubic yard
Step-by-step explanation:
![volume \: of \: pyramid \\ = area \: of \: base \times height \\ = {4}^{2} \times 3 \\ = 16 \times 3 \\ = 48 \: {yard}^{3} \\](https://tex.z-dn.net/?f=volume%20%5C%3A%20of%20%5C%3A%20pyramid%20%5C%5C%20%20%3D%20area%20%5C%3A%20of%20%5C%3A%20base%20%5Ctimes%20height%20%5C%5C%20%20%3D%20%20%7B4%7D%5E%7B2%7D%20%20%5Ctimes%203%20%5C%5C%20%20%3D%2016%20%5Ctimes%203%20%5C%5C%20%20%3D%2048%20%5C%3A%20%20%7Byard%7D%5E%7B3%7D%20%20%5C%5C%20)
SA: 2pi (r^2)+2pi(r)(h)
In order to find radius (r) of the base you must divide 10 by pi then find the square root of the result
√(10/pi)=r: 1.784cm
h: a) 8.0cm
b) 6.5cm
c) 9.4cm
2pi (3.183)+2pi(1.784)(8)=109.673cm^2
2pi (3.183)+2pi(1.784)(6.5)=92.859cm^2
2pi (3.183)+2pi(1.784)(9.4)=125.366cm^2
Slope-intercept form: y = mx + b
The answer is:
y = -5x - 1
