Hope this is correct Pls don`t kill me thx
Mom is 30 years old when Serena is 10 because 10 x 3 = 30.
They are 20 years apart. [This is key]
Half (.5) of mom's age will be = to Serena's age.
Therefore, when mom is 40 years old, Serena is 20 years old.
We can see that half of 40 = 20.
Hope this makes sense!

Step-by-step explanation:
A sector of a circle is the portion or region of a circle enclosed by two radii and an arc. The perimeter of a the sector of a circle is given by the formula:
Perimeter of sector = + 2r
Where θ is the angle which forms the sector and r is the radius of the circle.
Given that Perimeter of sector = 57.32 cm, radius (r) = 14 cm, we can find the angle θ using:
Perimeter of sector = + 2r
