Answer 2

Answer:

Step-by-step explanation:

Now we know that the Circumference or perimeter of the circle is 33.

Let the radius be "r". That is

2πr = 33

2*22/7*r=33

44/7r=33. Now we keep "r" there and bring 44/7 to the other side to divide with 33. That is

r = 33 divided by 44/7.

To divide a fraction, we must first multiply the second number's reciprocal. That is,

33*7/44

Now, we must cancel 33 and 44 by 11. That is

3*7/4 which is 21/4.

Now we know the radius.

Remember, we have to find the area.

So, the area of the circle = πr^2 = 22/7 *21/4*21/4

Note - "^" symbol means squared.

Multiply all 3 fractions and you get the answer which is

22/7 *21/4*21/4 = 693/8
