The formula for length of an arc on a circle is given by the formula:

L = \frac{2 \pi rx}{360},

where 'r' is the radius of the circle and 'x' is the measure of the central angle of the arc.

We have to determine the value of radius 'r'.

Since, L = \frac{2 \pi rx}{360}

By Cross multiplication, we get

360 \times L = 2 \pi rx

\frac{360 \times L}{ 2 \pi x} =r

\frac{180 \times L}{ \pi x} =r

r = \frac{180L}{ \pi x}

Therefore, the radius 'r' is given by r = \frac{180L}{ \pi x}.

Option 4 is the correct answer.

I got the opposite of this answer, it was instead "solve for x."

With anyone with this for their question, the answer is the opposite:

x = 180L/\pir

Thus x = 180L/pi<em> r</em>, looks just like D, but the "r" and "x" placements are switched.

How to do multiplication large numbers.
Keith_Richards [23]

Answer:

The main reason to know the multiplication table is so you can more easily multiply larger numbers. For example, suppose you want to multiply 53 x 7. Start by stacking these numbers on top of another, aligning the ones place. Draw a line underneath, and then multiply 3 by 7. Because 3 x 7 = 21, write down the ones digit (1) and carry the tens digit (2) to the tens column:

Next, multiply 5 by 7. This time, 5 x 7 = 35. But you also need to add the 2 that you carried over, which makes the result 37. Because 5 and 7 are the last numbers to multiply, you don’t have to carry, so write down the 37 — you find that 53 x 7 = 371:

When multiplying larger numbers, the idea is similar. For example, suppose you want to multiply 53 by 47. Be sure to align the stacked numbers by the ones place. (The first few steps — multiplying by the 7 in 47 — are the same, so pick up the next step.) Now you’re ready to multiply by the 4 in 47. But remember that this 4 is in the tens column, so it really means 40. So to begin, put a 0 directly under the 1 in 371:

This 0 acts as a placeholder so that this row is aligned properly.

When multiplying by larger numbers with two digits or more, use one placeholding zero when multiplying by the tens digit, two placeholding zeros when multiplying by the hundreds digit
