Let Hema's present age be x years.
After 15 years,her age will be (x+15) year.
according to the question ,
4x=x+15
4x−x=15
3x=15
x=5
Hence,Hema's present age is 5 years.

Answer:

Step-by-step explanation:

We can make this into the equation 25 + x = 4x

we isolate the equation by subtracting x from 4x. (3x)

Therefore, 25 = 3x. Therefore, Hema is 8.

A circle has a sector with area 33 pi and a central angle of 11/6 pi radians. What is the area of a circle?

Mashutka [201]

Answer:

36π

Step-by-step explanation:

The area of a circle is given as:

$A = \pi r^2$

where r = radius of the circle

The area of a sector of a circle is given as:

$A_s = \frac{\alpha }{2\pi} * \pi r^2$

where α = central angle in radians

Since $\pi r^2$ is the area of a circle, A, this implies that:

$A_s = \frac{\alpha }{360} * A$

A circle has a sector with area 33 pi and a central angle of 11/6 pi radians.

Therefore, the area of the circle, A, is:

$33 \pi = \frac{\frac{11 \pi}{6} }{2 \pi} * A\\\\33\pi = \frac{11}{12} * A\\\\=> A = \frac{33\pi * 12}{11}\\ \\A = \frac{396 \pi}{11} \\\\A = 36\pi$

The area of the circle is 36π.
