△def≅△pqr

what is the length of pq?

(df is 25cm and rq is 24cm)

Since the triangles are similar, they have the same ratio to all corresponding sides. Let's find the ratio of ΔDEF to ΔPQR.

DF/RQ = 25/24

Similarly,

DE/PQ = 25/24

Thus, 

PQ = 24/25 DE
PQ = 0.96DE

This means that the length of PQ is 96% of the length of DE. 

I hope I was able to help you. Have a good day.

Hello!

the answer is:

the correct option is the option b.

why?

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

The answer is d $21.65 i got that on a test in school before and got an a+ it should be d
