The surface area of a cylinder is:
A=2pr^2+2prh and since r=d/2
A=2p(d^2/4+dh/2)
A=(p/2)(d^2+2dh) and we need 200 of these cylinders...
A=(100p)(d^2+2dh), and using d and h, 3.5cm and 70cm we get:
A=(100p)(3.5^2+2*3.5*7)
A=(100p)(12.25+49)
A=6125p cm^2
A≈19242 cm^2 (to nearest cm^2)
Since 1 litre is 1000 millilitres, we can convert it to 1000 millilitres. So, we can subtract 375 millilitres from 1000 millilitres. Which will give us the answer of 625 millilitres.
Answer:
you will get a decimal answer which is 94.10526316
Step-by-step explanation:
A cube has 6 sides.
A cube is all made up of squares.
So, we need to find the area of one cube and multiply that by 6.
Length * width= area
40*40= 1,600
Multiply that by 6.
1,600*6= 9600
Whatever the unit is after that: in, feet, cm, m, etc- put that after the number with ^2.
9,600 (the unit) ^2
I hope this helps!

Answer:
6^8
Step-by-step explanation:
6^4 * 6^4
We know that a^b * a^c = a^( b+c)
6^(4+4)
6^8
