22x10= 220 for the area of the rectangle because basexheight= area and then take the triangle separately which is 7x10 multiplied by a half because the equation for the area of a triangle is base x height / 1/2

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
