A two digit number is 4 times the sum of its digits and twice the product of its digit.FIND THE NUMBER

Dmitrij [34]

X - tenths digit
y - units digit

$10x+y=4(x+y)\\
10x+y=2xy\\\\
10x+y=4x+4y\\
10x+y=2xy\\\\
6x=3y\\
10x+y=2xy\\\\
3x=y\\
10x+y=2xy\\\\
10x+3x=2x\cdot3x\\
13x=6x^2\\
6x^2-12x=0\\
6x(x-2)=0\\
x=0 \vee x=2\\\\
y=3\cdot2\\
y=6\\\\
10\cdot2+6=\boxed{26}$

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.
