A) If the perimeter of a circle is 44 cm,
(i) find its radius.
(ii) find its area.​

Let the length of radius of circle be rcm

Circumference of circle =2πr

Area of circle =

=

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
