Question

Find the area of a circle whose diameter is 16cm and arc PQ is 60°.

Answer 1

Radius = 8 cm.

Area = 60° / 360° • π • 64 = 33.5 cm ^2 approx.

Answer 2

Answer: d = 16

r = d/2 = 16/2 = 8

π = 22/7

∅ = 60° →→is not needed for circles area

→ area of circle = πr²

                         = 22/7 × 8 × 8 ⇒22/7 × 64

                         = 201.1

Step-by-step explanation:

so at first u take the given values,

in this the angle of the arc is not needed for finding the area of the circle.

this angle is used only for find area of sector,segment,etc.

then u subtitute the values in the formula

and simplify

and like that your final answer is 201.1
