Answer:

$\frac{C}{2\pi }=r$

Step-by-step explanation:

$C=2\pi r$

WE need to solve for 'r'. Our aim is to get 'r' alone

2πr mean 2 times pi times r

To remove 2π we do opposite operation

Opposite operation of multiplication is division.

To remove 2π , divide both sides by 2π

$\frac{C}{2\pi }=\frac{2\pi r}{2\pi}$

Now simplify it

$\frac{C}{2\pi }=r$

Solve for x. Evaluate and round your answer to 1 decimal place(tenths place). 10x=1200

Mandarinka [93]

Answer:

Step-by-step explanation:

<u>To solve first take logarithm to both sides</u>

That's

But

So we have

$x = log_{10}(1200)$

<u>Write 1200 as a number with the factor 100</u>

That's

1200 = 100 × 12

So we have

<h3> $x = log_{10}(100 \times 12)$ </h3>

<u>Using the rules of logarithms</u>

That's

<h3> $log_{a}(x \times y) = log_{a}(x) + log_{a}(y)$ </h3>

Rewrite the expression

That's

x = 3.079

So we have the final answer as

<h3>x = 3.1 to one decimal place</h3>

Hope this helps you
