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:an automatic stabilizer because it falls as income increases, slowing an economic expansion
Explanation:Unemployment Compensation are benefits provided by government to serve as a temporary income when one loses his or her job through no fault of him or her.
The money partly helps one pay expenses while looking for new job
Unemployment compensation is a fiscal policy used as an Automatic stabilizers to stabilise fluctuations in a nation's economic activity.
Similarly, Unemployment compensation payments, falls when the economy is in a phase of expansion since there are few unemployed people filing claims for compensation and rise when the economy is high in recession and high rate of unemployment IE when there are many people filing claims for compensation.

The answer that best complete the blank provided above is the term CANNIBALIZATION. Product cannibalization happens when a new product that is being introduced by the same producer, eats up the sales of the other products that exist in the same market resulting in the decrease of the overall sales.
