A circle has a radius of 6. An arc in this circle has a central angle of 48 degress. What is the length of the arc?
notsponge [240]

Answer: 1.6\pi

Step-by-step explanation:

If a circle has a radius of 6, then the perimeter of the circle is 12pi, or about 37.68.  A circle has 360 degrees.  Thus, the arc takes up 48/360 of the circle.  Thus, simply multiply \frac{48}{360} * 12\pi to get 5.024 or 1.6pi.

Hope it helps <3

The length of the top of a computer desk is 2 1/4 feet longer than it’s width. If it’s width measures y feet, express its length
Lera25 [3.4K]

Answer:

The length as an algebraic expression in y is  y   + (2\frac{1}{4} )  ft

Step-by-step explanation:

The measure of the width of the computer desk = y feet

The measure of the length of the desk = width + 2  1/4 ft

⇒Measure of Length = y   + (2\frac{1}{4} )   ft

Hence, the length as an algebraic expression in y is  y   + (2\frac{1}{4} )   ft
