34kurt

let's recall that a circle has a total of 360°.

now, Jack drew "27 out of 36", namely 27/36.

what's 27/36 of 360°? well, is simply their product.

$\bf \cfrac{27}{36}\cdot 360\implies 27\cdot \cfrac{360}{36}\implies 27\cdot 10\implies 270$

sphere and a cylinder have the same radius and height. The volume of the cylinder is 11 feet cubed. A sphere with height h and r

Fed [463]

Step-by-step explanation:

We have, a sphere and a cylinder have the same radius and height. The volume of the cylinder, $V_c=11\ ft^3$

The volume of sphere is : $V_s=\dfrac{4}{3}\pi r^3$

The volume of cylinder is : $V_c=\pi r^2h$

Dividing the volume of sphere and the volume and cylinder, such that,

$\dfrac{V_s}{V_c}=\dfrac{4\pi r^3}{3\pi r^2h}$

As r = h

$\dfrac{V_s}{V_c}=\dfrac{4}{3}\\\\V_s=\dfrac{4V_c}{3}\\\\V_s=\dfrac{4}{3}\times 11$

So, the volume of sphere is (four-third) of 11. therefore, the correct option is (A).

Divide. Write each quotient in simplest form.<br> 2/3 ÷ 2 = _____ Show step-by-step solution.

never [62]

The answer is $\frac{1}{3}$

$\frac{2}{3}$ ÷ 2 = $\frac{2}{3}$ ÷ $\frac{2}{1}$

If $\frac{a}{b}$ ÷ $\frac{c}{d}$ = $\frac{a*d}{b*c}$ , then:
$\frac{2}{3}$ ÷ $\frac{2}{1}$ = $\frac{2*1}{3*2}$

Now, 2 can be canceled out from $\frac{2*1}{3*2}$ :
$\frac{2*1}{3*2}= \frac{1}{3}$
