Find the volume of the cylinder.<br> Either enter an exact answer in terms of π or use 3.14 for π

Alex787 [66]

Answer:

Volume of the cylinder = $62.80 units^3$

Step-by-step explanation:

Height of the Cylinder(h)=5 units

Radius(r)=2 units

Volume of a cylinder= $\pi *r*r*h$

Putting the values in the formula;

Volume of the cylinder $=\pi *2*2*5$

As, $\pi =\frac{22}{7}=3.14$

Volume of the cylinder= $3.14*2*2*5$

$=3.14*2*2*5\\\\=3.14*4*5\\\\=3.14*20\\\\=62.80units^3$

The Volume of the cylinder is $62.80 units^3$

A water balloon is catapulted into the air so that it's height, in meters, after t seconds is h = -4.9t^ +27t +2.4

zysi [14]

$h = -4..9t^2+27t+2.4\ for\ t=3$

Just replace t with 3 and solve.

$h = -4.9*3^2 + 27*3 + 2.4 \\ h = -4.9*9 + 27*3 + 2.4 \\ h=-44.1 + 81 + 2.4 \\ \boxed{h=39.3}$

9 to the power 18 = 27 to the power x work out the value of x

Strike441 [17]

Answer:

Step-by-step explanation:

27^x = 9÷(3^x)

So (3^3)^x = (3^2)÷(3^x)

So 3^3x = 3^(2-x)

Comparing powers on both sides,

3x = 2 - x

So, 4x = 2

So, x = 1/2

Given ( 27 ) ^ x = 9 / 3 ^x

⇒ ( 3 × 3 × 3 )^x = ( 3 × 3 ) / 3^x

⇒ ( 3 ³ )^x = 3² / 3^x

⇒ 3 ^ 3x × 3^x = 3² [ since ( a ^m)^n = a ^mn ]

⇒ 3^ (3x +x) = 3² [ since a^m × a^n = a ^m+n ]

⇒ 3^4x = 3²

⇒4x = 2 [ since If a ^m = a ^n then m = n ]

⇒ x = 2 / 4

∴ x = 1 / 2

I hope this helps you.
