Answer:
942
Step-by-step explanation:
If 5 is the radius and 12 is the height, and the formula of a cylinder is V=πr^2h, we can substitute.
V=π(5)^2(12)
5^2 is 25, and 25 times 12 is 300.
300π, and that would be approximately 942.

Answer:
Part A: 12c sq. m
Part B: 6 sq. m
Step-by-step explanation:
Area of a rectangle = l X b sq. units
Part A:
Given Length , l = 6c units.
And Breadth, b = 2 units.
Hence, the area = 6c X 2 sq. units
Area, A = 12c sq. units
Part B:
When c = 
From Part A, we have Area, A = 12c sq.units
When c =
, area =
sq. units.
Therefore, Area = 6 sq. units.
10y² - 4x² = 2(5y² - 2x²)
16y² - x² = (4y + x)(4y - x) ................this is a difference of squares!
8x² - 40x + 256 = 8(x² - 5x + 32)
4x² - 48x + 9
