Answer:
1155.52
Explanation:
because the formula is 2πrh+2πrsquared
so 2(3.14)(8)(15)+2(200.96)= 1155.52
and you get 200.96 by doing your circle formula for area , which is A=πrsquared
In all energy transfers, if no energy leaves or enters the system, then the potential energy will always be less.

Answer:
Kinetic energy = 35840 Joules
Explanation:
Given the following data;
Mass = 70kg
Velocity = 32m/s
To find the kinetic energy;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where, K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
K.E = 35840 Joules.
Therefore, the kinetic energy possessed by the cheetah is 35840 Joules.
