Question

in a circle with centre o.the area of sector oAPB is 5/18 of the area find the area of x

Answer 1

Solution:-
There is a mistake in the question. It is not the area of x, that is to be find out, but instead the value of x is to be find out.
Area of the sector OAPB = x/360 × πr²
Now, according to the question.
Area of the sector OAPB = 5/18 of the area of the circle.
⇒ x/360 × πr² = 5/18πr²
⇒ x/360 × 5/18
⇒ 18x = 360 × 5
⇒ x = 1800/18
x = 100°
Answer.

Answer 2

Therefore the value of theta is 100..
