C=2pir, so take half of 15 which is 7.5 and plug it in as r and you get 47.12. Or just look up circumference calculator on google.
Answer:
19x
Step-by-step explanation:
product means multiply
19*x
19x
Answer:
15
Step-by-step explanation:
Given:
The point is (-12,-8).
Rule of transformation is
.
To find:
The coordinates of image after transformation.
Solution:
According to the rule of transformation
, first the point is dilated by factor
with origin as center of dilation after that it was rotated 270 degrees anticlockwise.
If a point is dilated by factor
with origin as center of dilation, then
If a point is rotated 270 degrees anticlockwise, then



Therefore, the coordinates of image after transformation are (-2,3).
Set up a proportion.
(8.75/5)=(x/2)
5x=2*8.75
5x = 17.5
x= 3.5
