Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80
Answer:
Option A
Annette picked 50 roses from the garden
Step-by-step explanation:
Let us understand the problem, designating letters to represent unknown quantities.
Let the total number of roses = x
