Alright, lets get started.
Numbers of visitors on Monday = 400
Numbers of visitors on Tuesday = 780
So, percentage change =
So, percentage change =
So, percentage change = 95 % : Answer
If same estimated percentage increase on next day also, means on Wednesday, the number of visitor will be = %
So,number of visitors on Wednesday =
Number of visitors on Wednesday = 1521 : Answer
Answer:
67.5π m²
Step-by-step explanation:
See the diagram given with the question.
The angle moved by the radius line about the center to cover the shaded region is 300°.
As the radius(r) is known to be 9 m.
So, the area of the full circle is πr² = π × (9)² = 81π m².
Now, to cover the whole circle the radius line has to rotate 360° about the center.
Hence, for rotation of 360° the area obtained is 81π m².
Then for rotation of 300° the area obtained will be m². (Answer)
