If xh=10 feet and mxy =100 degrees then determine the arc length of xy
schepotkina [342]

Answer:

The arc length XY is equal to \frac{50}{9}\pi\ ft  or 17.4\ ft

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the circumference of the circle H

The circumference is given by the formula

C=2 \pi r

we have

r=xh=10\ ft

substitute

C=2 \pi (10)\\C=20\pi\ ft

step 2

we know that

The circumference of a circle subtends a central angle of 360 degrees

so

using proportion

Find out the length of the arc xy if the central angle is equal to 100 degrees

Remember that

m\angle XHY=arc\ XY=100^o ---> by central angle

\frac{20\pi}{360^o}=\frac{x}{100^o}\\\\x=20\pi(100)/360\\\\x=\frac{2,000}{360}\pi\ ft

Simplify

x=\frac{50}{9}\pi\ ft ----> exact value

To find out the approximate value

assume

\pi=3.14

substitute

x=\frac{50}{9}(3.14)=17.4\ ft ----> approximate value

therefore

The arc length XY is equal to \frac{50}{9}\pi\ ft  or 17.4\ ft
