Answer:
36π
Step-by-step explanation:
The area of a circle is given as:

where r = radius of the circle
The area of a sector of a circle is given as:

where α = central angle in radians
Since
is the area of a circle, A, this implies that:

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:

The area of the circle is 36π.
The are is eleven because 2×11= 22
Answer:
47.9 gm
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Total butter took = 54.8 gm
Extra butter quantity = 6.9g
So, we can calculate the exact quantity of butter needed by using following formula,
Exact butter needed = Total butter - Extra butter quantity
By putting the value, we get
Exact butter needed = 54.8 gm - 6.9gm
= 47.9 gm
Hence, he need 47.9gm butter.
