n² = 121

n = ...?

Use root tree :

121

/ \

11 11

11 × 11 = 121

11² = 121

So :

n² = 11²

n = 11

So, the value of n is 11

Hope it helpful and useful :)

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
