Question

in figure O is the centre of the circle if angle aob is equal to 90 degree and Angle Aoc equal to 150 degree the area of shaded part is how many percent of the area of a circle ​

Answer 1

Answer:

4.5π in^2

Step-by-step explanation:

The first thing to do is calculate the dimensions of the pizza box. Based on our data, we know 256 = s². Solving for s (by taking the square root of both sides), we get 16 = s (or s = 16).

Now, we know that the diameter of the pizza is four inches less than 16 inches. That is, it is 12 inches. Be careful! The area of the circle is given in terms of radius, which is half the diameter, or 6 inches. Therefore, the area of the pizza is π * 62 = 36π in². If the pizza is 8-slices, one slice is equal to 1/8 of the total pizza or (36π)/8 = 4.5π in².

Answer 2

Answer:

33.33%

Step-by-step explanation:

the remaining part is angle of 360°-150-90=120°

So, area will be angle covered by this part by total part

= $\frac{120}{360}*100=33.33$
