Answer:
<u>9π m²</u>
Step-by-step explanation:
We will need calculate the area of the top, the base and sides.
Area of the top=πr²
Area of the base=πr²
Area of the side: 2πrh
Surface area of a cylinder: area of the top + area of the base +area of the side
Surface area of a cylinder=πr²+πr²+2πrh=2πr²+2πrh=2πr(r+h)
Data:
r=1.5 m
h=1.5 m
Surface area of this cylinder=2π(1.5m)(1.5 m+1.5 m)=3π m*(3 m)=9π m².
The volume of a rectangular prism can be found by the formula:
V = A × h
Where:
A = area of the base of the prism
h = height of the prism
Therefore:
V = 450 × 53
= 23850 in³
The volume of the file cabinet is <span>23850 in³.</span>
Simply just divide there total investment for pizza with the cost for one small pizza 1100/4=275
275 Small pizzas were sold
Volume of a cylinder: pi*r^2*h
volume of a right cone: (1/3)*pi*r^2*h
the volume of the cylinder is triple the volume of the cone
it's 18 inch^3
