The left side is a half circle.
The area of a circle is PI x r^2
The diameter of the circle would be the height of the rectangle, given as 10 feet.
The radius is 1/2 the diameter, so 5 feet.
The area of half the circle is (3.14 x 5^2) / 2 = 39.25 square feet.
The area of the rectangle is 20 x 10 = 200 square feet.
Total area = 200 + 39.25 = 239.25 square feet.
Answer:
d
Step-by-step explanation:
Circles with the same centre are concentric circles
The total number of persons standing in the line waiting for ordering pizza are 5.
Explanation:
There are 5 people in total so the first place can be occupied by any of the 5 persons.
Secondly the second place in the line can be occupied by any of the 4 persons left.
Then the third place will be occupied by any remaining 3 persons as the front two places are already occupied.
Similarly the fourth place will be taken by any of the remaining two people. And lastly the last place will b filled by the last remaining person.
So the total number of ways will be 5*4*3*2*1 = 120 ways that is given in the question.
