Question

Help me pls let me know if my answer is right or not if not pls let me know the correct answer. ASAP

Answer 1

The correct answer is 7.5

Answer 2

7.5

Explanation:

Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:

270/360; 360 being the total angle measurement of a circle

270/360 simplifies to 3/4

The fraction represents how much of the circle that arc covers

Now we have to find the circumference which would be

2(
`\pi \\`)r

r = 5 therefore: 2(
`\pi \\`)5 = 10
`\pi \\`

Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length

Which gives us 7.5
`\pi \\`, or 23.55
