So what you are looking for is the hypotenuse of the triangle DCF.
We know DC is 3cm, so we need CF.
BC and CF and CF create a right triangle.
Using Pythagorean Theorem, CF is about 10.2
Now using Pythagorean Theorem again, 3^2 +10.2^2=113
The sqaureroot of that is 10.6. So 10.6 is your answer
It's al little over 190. you just divide the 1000 by the 5.25%.
So lets just simplify them first
1 batch = 2 3/4 so...
11/4 cups
and you need to make 3 1/2 batch so..
7/2 batch
then you just multiply it...
11/4 x 7/2
=77/8
=9 5/8
so you will need 9 5/8 cups
7(a - 10) = 13 - 2(2a + 3)
7a - 70 = 13 - 4a - 6 = 7 - 4a
7a + 4a = 7 + 70
11a = 77
a = 77/11 = 7
a = 7.
Area of the sheet used to make the tank = total surface area of the cylinder = 2
r(r+h) = 2 x 22/7 x 63 x 263 = 104148 sq. cm.
