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:
8
Step-by-step explanation:
If we assume the '17' is the hypotenuse ( the Q does not say)
then 15^2 + x^2 = 17^2 via the pythag theorem for right triangles
x = 8
Answer:$15.40
Step-by-step explanation:
Answer:
Not enough information
Step-by-step explanation:
You gave the height, but there is no length. You need both the height and length because the area of a triangle is 1/2bh
