This would be a rational number, for it equals 0.875
8 and 9
9^3-8^3
729-512
=169
Formula C= 2(3.14)(R)
We are looking for R first, so
=
——
2
r= 25.12
————
2(3.14)
r= 25.12
———-
6.28
r= 4
diameter= r(2)
4(2)= 8
THE DIAMETER OF THE CIRCLE IS 8
Answer:
Step-by-step explanation:
If AD=DB and AE=EC,
then DE¯¯¯¯¯∥BC¯¯¯¯¯ and DE=12BC .
Answer:
- True, True, False, False, True
Step-by-step explanation:
Trapezoid ABCD was dilated to create trapezoid A'B'C'D'.
Scale factor is 1/2 according to the coordinates.
<h3>The answer options</h3>
<u>The length of side AD is 8 units.</u>
<u>The length of side A'D' is 4 units.</u>
<u>The image is larger than the pre-image.</u>
- False. It is 2 times smaller.
<u>Sides CD and C'D' both have the same slope, 2.</u>
Slopes of CD and C'D' are same: m = (0 - 4)/(4 - 2) = -4/2 = -2
<u>The scale factor is One-half.</u>
