A platinum cylinder has a mass of 1.000 kg, a diameter of 3.90 cm, and a height of 3.90 cm. What is the volume of the cylinder in cubic centimeters? The volume of a cylinder equals pie(d)^2h/4, where pie is 3.14, d is diameter, and h is the height.

b i think it’s a water wheel turning in a stream

i believe the answer is a.

it takes on an electronical energy

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
