The formula of an area of a rhombus:

$A=\dfrac{diagonal_1\cdot diagonal_2}{2}$

The diagonals bisect each other. That is, they divide each other into two equal parts.

Therefore we have:

$diagonal_1=2\cdot1.2m=2.4m\\\\diagonal_2=2\cdot0.9m=1.8m$

Substitute:

$A=\dfrac{2.4\cdot1.8}{2}=2.16\ m^2$

Answer: 2.16 m²

What is the approximate area of the shaded sector in the circle shown below?

Strike441 [17]

Answer:

Correct option is B.

Step-by-step explanation:

Given the radius of circle and the angle in sector we have to find the area of shaded region i.e minor sector.

$Radius=r=16 in.$

$Angle=\theta=110^{\circ}$

$Area of sector=}\frac{\theta}{360}\times\pi r^2$

$=\frac{110}{360}\times\frac{22}{7}\times(16)^2$

$=\frac{11}{36}\times \frac{22}{7}\times 16\times 16=245.841=246(approx.)$

∴ Area of sector is $246in^2$

Correct option is B.
