Step-by-step explanation:
this photo is correct answer of this question.
The answer is r and s because it’s in the same plane.
Answer:
36π
Step-by-step explanation:
The area of a circle is given as:
![A = \pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2)
where r = radius of the circle
The area of a sector of a circle is given as:
![A_s = \frac{\alpha }{2\pi} * \pi r^2](https://tex.z-dn.net/?f=A_s%20%3D%20%5Cfrac%7B%5Calpha%20%7D%7B2%5Cpi%7D%20%2A%20%5Cpi%20r%5E2)
where α = central angle in radians
Since
is the area of a circle, A, this implies that:
![A_s = \frac{\alpha }{360} * A](https://tex.z-dn.net/?f=A_s%20%3D%20%5Cfrac%7B%5Calpha%20%7D%7B360%7D%20%20%2A%20A)
A circle has a sector with area 33 pi and a central angle of 11/6 pi radians.
Therefore, the area of the circle, A, is:
![33 \pi = \frac{\frac{11 \pi}{6} }{2 \pi} * A\\\\33\pi = \frac{11}{12} * A\\\\=> A = \frac{33\pi * 12}{11}\\ \\A = \frac{396 \pi}{11} \\\\A = 36\pi](https://tex.z-dn.net/?f=33%20%5Cpi%20%3D%20%5Cfrac%7B%5Cfrac%7B11%20%5Cpi%7D%7B6%7D%20%7D%7B2%20%5Cpi%7D%20%2A%20A%5C%5C%5C%5C33%5Cpi%20%3D%20%5Cfrac%7B11%7D%7B12%7D%20%2A%20A%5C%5C%5C%5C%3D%3E%20A%20%3D%20%5Cfrac%7B33%5Cpi%20%2A%2012%7D%7B11%7D%5C%5C%20%5C%5CA%20%3D%20%5Cfrac%7B396%20%5Cpi%7D%7B11%7D%20%5C%5C%5C%5CA%20%3D%2036%5Cpi)
The area of the circle is 36π.
Answer:
20) 2/32 so colour 2 boxes
21) 7/16
22) 2/60
23) 3/8
24) 35/63 or 5/9
25) 7/32
26) 45/60 or 9/12 or 3/4
27) 1/32
28) 3/21 or 1/7
29) 13/6 × 9/2
= 117/12
30) 3/4 × 17/2
= 51/8
31) 9/8 × 10/3
= 90/24
= 45/12
= 15/4
32) 16/5 × 2/3
= 32/15
sorry if theres any calculation mistake becoz i did all the calculations in mind
