He circumference of a circle<span> is equal to the diameter times pi. So, let's look at </span>what happens<span> if you double the </span>radius<span> of a </span>circle<span> -- say from 2 to 4. The area will go from 12.56 to 50.24. This means that it has </span>quadrupled<span>.</span>

Circumference = 2 * PI * radius
The circumference would also be quadrupled.
There is a direct relationship between circumference and radius.

answer is 25

Step-by-step explanation:

for something like this you need to use the law of sins. First identify all the angles. There is a 90 degree angle and a 59 degree angle and those are clear. the missing angle is = 59 + 90 = 149

since a triangle has 180 degrees in total you say 180 - 149 = 31. the missing angle is 31 degrees. so we give the angles names. angle with 59 degrees will be angle A, 90 will be B and 31 will be C. So now we just give the sides names. let's replace that x with an a since it's across angle A. the side along angle B will be named b and the side along angle C will be named c. so you say:

Sin A/ a (sin A over a) = Sin B/b = Sin C/c

Sin A is what we are looking for so we say

59 degrees over/ x = sin 31 degrees/ 13 (we leave out the 90 degrees since we don't know the side and also we are not interested in it)

now we do cross multiplying.

say x ×sin 31 degrees = 13× sin 59

now divide these by sin 31

x = 13 × sin 59 ÷ 31 = 25

Answer:

Step-by-step explanation:

I'm assuming that your "70=50x what is xx" actually means "find x if 70-50x = 0"  If that's not what you meant, please retype your question.

Dividing both sides by -50 results in -70/50 + x = 0, and adding 70/50 to both sides results in x = 70/50, or 7/5.

Only if my assumptions are correct:  x = 7/5.
