The face of a clock has a circumference of 63 in. what is the area of the face of the clock?

The area of the clock

Step-by-step explanation:

We have been given the face of the clock that is

So that is also the circumference of the clock.

Since the clock is circular in shape.

So

From here we will calculate the value of radius of the clock that is circular in shape.

Then

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now

So the area of the face of the clock =

9 x 8 divided by (5-3)=36

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
