Answer:
27.19 cm.
Explanation:
From the question given above, the following data were obtained:
Height (h) of cylinder = 6461.76 cm
Volume (V) of cylinder = 15000000 cm³
P1 (π) = 3.14
Radius (r) =.?
Thus, we can obtain the radius of the cylinder water tank by using the following formula as illustrated below:
V = πr²h
15000000 = 3.14 × r² × 6461.76
15000000 = 3.14 × 6461.76 × r²
Divide both side by 3.14 × 6461.76
r² = 15000000 / (3.14 × 6461.76)
Take the square root of both side
r = √[15000000 / (3.14 × 6461.76)]
r = 27.19 cm
Thus, the radius of the cylinder water tank is 27.19 cm.

Answer:
Copper
Explanation:
Metals are often arranged in crystalline lattices. The lattice consists of metal ions with an overlying sea of electrons. The conductivity of a metal depends on the nature of this crystal lattice. Naturally, some metals conduct electricity better than others. The unique properties of the crystal lattice of copper allow electrons to flow through it freely especially when it is drawn into a wire.
