If U=pi(r+h),find r when U=16 1/2 and h=2<br> solve this question by take the value of pi 22/7

I am Lyosha [343]

$U=\pi (r+h) \\\\ 16 \frac{1}{2}= \frac{22}{7}\cdot (r+2) \\\\ \frac{33}{2} : \frac{22}{7}=r+2 \\\\ \frac{\not 33}{2}\cdot \frac{7}{\not 22}=r+2 \\\\ \frac{3}{2} \cdot \frac{7}{2}=r+2 \\\\ \frac{21}{4}=r^{(4}+2^{(4} \\\\ 21=4r+8 \\\\ 4r=21-8 \\\\ 4r=13 \\\\ \boxed{r=\frac{13}{4}}$

Write a let statement, an equation, solve: Jeremy is 14 years old. This is 4 1/2 years more than half his sisters age. How old i

Art [367]

J = 14
J = 1/2S + 4 1/2

14 = 1/2S + 9/2....multiply everything by 2 to get rid of fractions
28 = S + 9
28 - 9 = S
19 = S

check...
14 = 1/2S + 9/2......S = 19
14 = 1/2(19) + 9/2
14 = 9 1/2 + 9/2
14 = 19/2+ 9/2
14 = 28/2
14 = 14 (correct)

so the sister is 19 <===

Which expressions can be used to compute the approximate area of triangle XYZ? Check all that apply.

lesantik [10]

Given:

In the given ΔXYZ,

Base = 22

Height = 23.1

Also,

Base = 31.9

Height = 15.9

To find the area of the given ΔXYZ.

Formula

The area of a triangle is

$A = \frac{1}{2} bh$

where, b be the base and

h be the height.

Now,

Taking, b = 22 and h = 23.1 we get,

$A = \frac{1}{2} (22)(23.1)$ sq unit

Again,

Taking,

b = 31.9 and h = 15.9 we get,

$A = \frac{1}{2} (31.9)(15.9)$ sq unit

Therefore,

We can find the approximate area of the triangle by following two expression

a) $\frac{1}{2} (22)(23.1)$ and

b) $\frac{1}{2} (31.9)(15.9)$

Answer:

<em /> $\displaystyle r=\sqrt[3]{\frac{3V}{4\pi}}$ <em />

<em>The last option matches the correct solution</em>

Step-by-step explanation:

<u>Equation Solving</u>

We have the following equation:

$\displaystyle V=\frac{4}{3}\pi r^3$

And it's required to solve it for r.

Solving this equation needs to perform some operations to have the r isolated from any other variables or constants.

It can be done by conveniently operating on both sides as follows:

Eliminate the denominator by multiplying by 3:

$\displaystyle 3V=4\pi r^3$

Move $4\pi$ to the other side by dividing by $4\pi$ :

$\displaystyle \frac{3V}{4\pi}= r^3$

Swapping sides to have r at the left side:

$\displaystyle r^3=\frac{3V}{4\pi}$

Finally, take the cubic root and leave r alone:

$\displaystyle r=\sqrt[3]{\frac{3V}{4\pi}}$

The last option matches the correct solution
