Find the area of the shaded sector.
Vladimir [108]

Given that,

Radius of the circle, r = 8.91 cm

Angle, \theta=81^{\circ}

To find,

The area of minor sector.

Solution,

The formula for the area of minor sector is given by the formula as follows :

A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{81}{360}\times \pi \times (8.91)^2\\\\A=56.11\ \text{cm}^2

So, the area of the shaded sector is 56.11\ \text{cm}^2.

What is the present age of Alex if he is one- fourth the age of a his father and if the age of the father is doubled, it is 20 y
AURORKA [14]

take father's age as x

if it is doubled i.e 2x .we get the answer as 20 less than 100 which means 100-20=80

accordingly the equation will be 2x=80

x=40

given that ,

son is 1/4 th of his father

hence ,

son = 1/4×(x)

I.e, 1/4×40 =10

Hope it helps
