Answer:
Step-by-step explanation:
Radius r = 15
Circumference = 2πr = 30π cm
Circumference of cone = arc length of sector
= 30π × 216°/360°
= 18π cm
Radius of base of cone = 18π/(2π) = 9 cm
Slant height of cone = radius of circle = 15 cm
Height of cone = √(15² - 9²) = 12 cm
The first one is 24 the second is 96
This is my answer - a beautiful image. You haven’t attached the image to determine the answer, please do!
For the first equation, I put it in y=mx+b form, so y=-3x-9
the second one is x=4
hope i helped
