Answer:
The volume of cone is increasing at a rate 1808.64 cubic cm per second.
Step-by-step explanation:
We are given the following in the question:
Volume of cone =
where r is the radius and h is the height of the cone.
Instant height = 9 cm
Instant radius = 6 cm
Rate of change of volume =
Putting values, we get,
Thus, the volume of cone is increasing at a rate 1808.64 cubic cm per second.
Answer:
Angle(APR) = 43
x = 21.5
Step-by-step explanation:
The given angles are complementary :
So APR + RPW = 90
APR = 43
2x = 43
x = 21.5
Answer:
Adults = x
Students = y = x + 40. 40 more student than adult
Adult = $8, Student = $6
Total for Adults = 8*x = 8x
Total for students = 6*y = 6y
Total = $1920
8x + 6y = 1920
Hence system of equations are:
y = x + 40
8x + 6y = 1920
3.45 rounded to the nearest whole number would be 3 because 5 or more let it soar 4 or less let it rest
