The true statement is (a) segment BC is located at B (1, 0) and C (1, 3) and is one-half the size of segment B'C'
The coordinates are given as:
The scale factor from BC is given as:
So, the coordinates of segment BC are calculated using:
This gives
Divide both sides by 2
Also, we have:
Divide both sides by 2
Hence, the true statement is (a)

Answer:
a) 3.39 cm b) 21.29 cm
Step-by-step explanation:
ok so the area of a circle is r^2.
if the area is 36 cm^2 we can divide it by 3.14, which is pi (). that gives us 11.46. now we find the approximate square root of this.
this is approximately equal to 3.39. the radius is about 3.39cm.
now that we know the radius, we can easily find the circumference. the formula for this is d. the diameter is just the radius times 2. (3.39)(2)
we plug the numbers into the formula: 3.14(6.78)=21.29 cm =d
