Question

Find the length od ypx. Leave your answer in terms of pi

Answer 1

your answer is

b = 15 pi

length of ypx = circumfrance of circle - 1/4 of circumfrance of circle

= 2pi r - 2pi r/4 = 6 pi r / 4 = 3 pi r / 2

= 3 pi × 10/2 = 15 pi

Answer 2

Answer:

b. 15π m  

Step-by-step explanation:

The formula for the arc length (s) of a circle is  

s = rθ

Data:

r = 10 m

Calculations:

The smaller angle is π/2.

The angle θ subtending XPY is 2π - π/2 = (3π)/2.

s = rθ = 10 × (3π)/2 = 15π m

The length of XPY is 15π m.
