The surface area of a cylinder is:
A=2pr^2+2prh and since r=d/2
A=2p(d^2/4+dh/2)
A=(p/2)(d^2+2dh) and we need 200 of these cylinders...
A=(100p)(d^2+2dh), and using d and h, 3.5cm and 70cm we get:
A=(100p)(3.5^2+2*3.5*7)
A=(100p)(12.25+49)
A=6125p cm^2
A≈19242 cm^2 (to nearest cm^2)

Answer:
15 : 1
Step-by-step explanation:
Each kg is 1000 g, so the ratio is ...
3000 g : 200 g = 30 : 2 = 15 : 1
3 kg is 15 times 200 g.
Answer:
y=2x-4
Step-by-step explanation:
slope=2=k
y-intercept in - 4 then n=-4
y=kx+n
y=2x-4
Answer:
I say the answer is ball 4
Step-by-step explanation:
The reason why I chose ball 4 was because ball 4 has less mass and the mass for ball 4 is only 300 and I'm pretty sure if you rolled ball 4 it would've went the farthest because it's mass is lesser than the others.
