Answer:
dv= 989100cm^3
Explanation:
The volume of a sphere can be calculated using below formula
Volume of a sphere = 4/3 π r^3
Therefore, for a hemisphere, V= 2/3 pi r^3
V=(4/3)πr³
V= 2/3πr³
dV/dr=4πr²
Then we need to pproximate dV/dr with
ΔV/Δr then we have
Volume of hemispherical some is one half of the the volume of a sphere where dr is change in radius, dv is change in volume
dV/dr=2πr²
Take the derivative of V with respect to r then we have
dV=2πr²dr
where
Radius = diameter/2
Our diameter is 30cm then
r=30m/2 = 15cm
Then we convert to cm we have
r= 1500cm
dv= 2×π ×(1500)^2 × 0.07
dv= 989100cm^3
the amount of paint in cubic centimeters needed to apply a coat of paint 0.07 cm thick to a hemispherical dome with a diameter of 30 meters is
989100cm^3
Answer:
Jim C. Collins.
Explanation:
Jim C. Collins is a writer and researcher who identifies five levels of leadership: executive, effective leader, competent manager, contributing team member, and highly capable individual. He was an American writer, speaker and researcher born on the 25th of January, 1958. Most of his notable works were on organizational sustainability, business management and growth.

1. Highly capable individual.
2. Contributing team member.
3. Competent manager.
4. Effective leader.

Answer:
The correct answer is letter "B": Firms whose fixed assets are "lumpy" frequently have excess capacity, and this should be accounted for in the financial forecasting process.
Explanation:
Lumpy assets are assets that must be acquired in large-discrete units, not in small units. This causes excess capacity which is the situation in which the production is less than reachable for a firm. In the market, the demand is lower than what the firm could supply. This problem should be considered in a financial forecasting process to predict what the consequences could be in the long-term.
