Answer:
27
Step-by-step explanation:
3x + 9 = 90
3x = 81
x = 27
To find y-intercepts, you substitute in 0 for X
2y-5x=16
2y-5(0)=16
2y-0=16
2y=16
Y=8
So the y-intercept is (0,8)
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:
