What is the volu ne of the cylinder? Use 3.14 for it, and round your answer to the nearest tenth.
bearhunter [10]

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.

Can someone PLEASE HELP ME

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 = $ \frac{\textbf{1}}{\textbf{2}} $

From Part A, we have Area, A = 12c sq.units

When c = $ \frac{1}{2} $, area = $ 12 \bigg ( \frac{1}{2} \bigg ) $ 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)
