How do you solve for r in the formula a=pi r squared

1 answer:

7 0

To solve for y, all you have to do is just separate r from all of the others and make it equal to the rest of the equation. So first it was, a=pi*r squared.
Divide by pi on each side,
a/pi=r^2
Take the square root of each side;
square root of (a/pi) =r
and that's all
Hope this helps.

Answer:

$f(0) = 14$

Step-by-step explanation:

Given

$f(x) = \left \{ {{|x - 8| + 6 \ x$

Required

Find f(0)

From the piecewise function, we have the following as values of f(x):

$f(x) = |x - 8| + 6$

If $x < 4$

$f(x) = 15$

If $x \ge 4\\$

f(0) implies that $x =0$ and $0$

So, we make use of the first function, which is:

$f(x) = |x - 8| + 6$

Substitute 0 for x in $f(x) = |x - 8| + 6$

$f(0) = |0 - 8| + 6$

$f(0) = |- 8| + 6$

$|-8| = 8$

So, the expression becomes

$f(0) = 8 + 6$

$f(0) = 14$

<em>Hence, the value of f(0) is 14</em>

Mae Ling earns a weekly salary of $375 plus a 7.0% commission on sales at a gift shop. How much would she make in a work week if

pentagon [3]

Answer:

$697

Step-by-step explanation:

Given that :

Weekly earning = $375 plus 7% commission on sales

Earning if she sold $4600 worth of merchandise

Commision on sales = 7% of 4600

Commission = 0.07 * 4600

Commission on sales = $322

Total earning = $375 + $322

Total earning = $697

A race is 3 miles long. There are water stations every 3/4 mile along the route. How many water stations are along the route?

Vilka [71]

There will be 4 water stations.

Why?

3/4 = .75 as a decimal

Personally, I believe that it’s easier to use decimals, I can explain the way in fractions in the comments if you’d like, just ask.

Anyway, .75 • 4= 3

or 3 / .75 = 4 (division is easier with bigger numbers)

so, there will be 4 water stations, given that the one race is 3 miles long.

If this explanation seems unclear, I’d be happy to explain. Feel free to ask in the comments!! I’m happy to help.

Hope this helps!
