A spider crawls though an arc of 50 degrees. How far does the spider crawl if the diameter of the circle is 100 inches?

There are 360 degrees around a circle. So first find the circumference of the circle and then divide it by 360 which will give 1 degree of distance and then multiply this by 50 to show how far the spider crawled:

Circumference = 100*pi

1 degree = (100*pi)/360 = 5/18*pi

Distance crawled = 50*5/18*pi = 43.6332313 inches

Answer: 44 inches to the nearest inch.
