I think it's D. 78.5 in²

Step-by-step explanation:

The area of a circle is pi r², but since we replace pi with 3.14, it is 3.14r².

The radius is 5, so we can replace r with 5.

We now have 3.14(5²). 5² is 25, so we now have 3.14(25).

3.14 × 25 = 78.5.

Hope this helps.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
