Answer:
9 cm
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
so

substitute the given values

solve for YZ

For this case we have by definition, that the circumference of a circle is given by the following formula:

Where:
d: Is the diameter of the circumference
So:

Rounding to a decimal we have:

ANswer:

For every c substitute 4 and for every d substitute -2
c=4
d=-2
6c + 5d - 4c - 3d + 3c - 6d
= 6(4)+ 5(-2)- 4(4)- 3(-2)+ 3(4)- 6(-2)
=24+(-10)-16-(-6)+12-(-12)
=24-10-16+6+12+12
=28
