Answer:
$5202
Step-by-step explanation:
The total surface area of the cuboidal hall is:
2LB + 2BH + 2LH.
This will be: 2(40*3) + 2(3*15) + 2(40*15)
which will give : 1530m square.
The cost of 25msq of paint is 10
then the cost of 1530 will be 1530x10/25 = 612.
The cost of 1msq of tiles is 3
then the cost of 1530 will be 1530 x 3
= 4590.
Then the total cost will be =$5202

Answer:
54461.33 cubic feet
Step-by-step explanation:
Given data
Height of cylinder= 40 feet
Radius= 20feet
Height of cone= 10 feet
Radius of cone= 20feet
Volume of Cylinder= πr^2h
Volume of Cylinder= 3.142*20^2*40
Volume of Cylinder= 3.142*400*40
Volume of Cylinder= 50272 cubic feet
Volume of Cone= 1/3πr^2h
Volume of Cylinder= 1/3*3.142*20^2*10
Volume of Cylinder= 1/3*3.142*400*10
Volume of Cylinder= 1/3*12568
Volume of Cylinder=4189.33 cubic feet
Hence, the volume of the silo = volume of cylinder+ volume of cone
Volume of silo= 50272+4189.33
Volume of silo=54461.33 cubic feet
Answer:
There isn't a plot
Step-by-step explanation:
<span>Mica should have added 2 to 3 instead of 1 to 3.
She factored out a 2 on the righthand side, so adding 1 within the parentheses is equivalent to adding 2 outside the parentheses. Since this is an equation, what we do to one side, we must do to the other, so Mica should've added 2 to the lefthand side.</span>
