What is the area of a circle with a diameter of 13.2 cm?

Use 3.14 for Π and round your final answer to the nearest hundredth.
Question 3 options:

547.11 cm2

136.78 cm2

41.45 cm2

20.724 cm2

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

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
