Step-by-step explanation:
V = (1/3) pi r^2 h where r is the radius of the circular base and h is the height of the cone.
V = (1/3) pi (15)^2 * 9
V = 675 pi
V = 2120,575 square cm (approx)
Answer:
A) car one is linear because it decreases the same amount every year.
car two decreases by the same ratio so it's exponential.
B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)
for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)
C) after 5 years car one will be 8,000
after 5 years car two will be about 16,860
