Surface area of a right cone is defined by: SA = πr² + πrl where r is the radius and 'l' is the slant height of the cone.
SA = π(17)² + π(17)(34)
SA = 289π + 578π
SA = 867π cm²
<span> i think that -1 is the answer </span>
Answer:
What do i do???
Step-by-step explanation:
if your book scales 10 times then each surface will scale 10^2=100 times. so the total surface would be 100*126.25=12625
