What is the length of XPY in terms of pie?
A) 30 pi m
B) 10 pi m
C) 300 pi m
D) 100 pi m
Answer:
A
Step-by-step explanation:
The angle subtended at the centre of the circle by arc XPY is 270°
That is 360° - 90° = 270°
arc length = circumference × fraction of circle
= 2πr ×
= 2π × 20 ×
= 40π × = 30π m → A
