Answer:

25.12

Step-by-step explanation:

So if the diameter is 16, then the radius is 8.

To find the area we need to do 3.14*8²=200.96

200.96 is the area of the whole pizza, so if there are 8 slices and we want to find the area of one slice, divide the total by 8.

200.96/8=25.12.

Hope this helps, please put brainliest if you can!

Answer:

The correct option is 1 and 4 are correct.

Step-by-step explanation:

The dilation is the enlargement and comparison of a figure according to the scale factor from the given center of dilation.

The rule DO,2(x,y)(2x,2y) express the dilation with factor 2 and the center of dilation is origin. It shows the enlargement of the triangle. The sides of image is twice of the preimage.

In dilation the corresponding angles remains same and the corresponding sides are equal.

\angle P=\angle P'

\angle PQR=\angle Q'

\angle R=\angle P'QQ'

PR=P'Q

PQ=P'Q'

RQ=QQ'

Therefore option 1 and 4 are correct.

Erin is 8 years younger than twice Paula’s age. The sum of their ages is 40. How old is Erin
Lina20 [59]
You do the sum(40) subtracted by 8, the answer from that divided by 2 since Erin's two times younger.
40-8=32
32÷2=16
Then if you want to check it you do the opposite and get the same sum(40) so 16×2=32 and 32+8=40
