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:
Equity account
Explanation:
In the case when the cash is received in exchange of the common stock so here the cash is debited and credited the common stock i.e. equity account
The journal entry is
Cash Dr XXXXX
To Common stock XXXXX
(Being exchange is recorded)
here cash is debited as it increased the assets and credited the common stock as it also increased the equity
Cost behavior analysis refers to management’s attempt to understand how operating costs change in relation to a change in an organization’s level of activity.
Fixed and variable cost behaves:-
- This cost behavior design is called a variable cost.
- A variable taken a toll portrays a taken a toll that changes in add up to with changes in volume of action.
- The movement in this case is the number of bicycles delivered and sold. Be that as it may, the movement can take numerous distinctive shapes depending on the organization.
- The two most common variable costs are coordinate materials and coordinate labor. Other cases incorporate roundabout materials and vitality costs.
- This cost behavior design is called a settled fetched.
- A fixed cost depicts a fetched that's fixed (does not alter) in add up to with changes in volume of action.
- Expecting the action is the number of bicycles delivered and sold, illustrations of fixed costs incorporate salaried staff, building lease, and protections.
