Because 843,000 is closer to 840,000 than 850,000
you'd use the pythagorean theorem.
a^2+b^2=c^2
a is the first leg, b is the second leg, and c is the third leg.
10^2+13^2=c^2
100+169=c^2
269=c^2
take the square root of both sides
16.4=c
16.4cm is your answer!

Answer:
118.6 or 119
Step-by-step explanation:
you just add and round up
Formula: SA = 2πr² + 2πrh
h =40 in
Diameter d =12 in.
Radius = r = d/2 = 12/2 = 6 in
SA = 2π6² + 2π*6*40 = 72π + 480π = 552π (in²)
SA = 552π = 552*3.14 = 1733.28 (in²)
Answer: 1733.28.
