Volume of the cylinder = πr²h = π(1)² (21) = 21π cm³
Volume of the cone = 1/3 π r² h
21π = 1/3 π (r)² (7)
r³ = 21π ÷ (7/3 π)
r² = 9
r = 3
Answer : Radius = 3
Answer:
When two atoms have shared electrons, it is not distinguishable from what atom they are because they are shared in the same orbit, it is called a covalent bond.
Step-by-step explanation:
Atoms in a covalent bond share one or more electrons in the last of their orbitals, the number of electrons in the last orbital will depend on the element in question.
5 * 12 = 60 (for the whole area)
3 * 2 = 6 (for the missing space)
6 + 2 = 8
12 - 8 = 4
4 * 3 = 12
12 / 2 = 6
6 + 6 = 12
60 - 12 = 48
Answer: 48
Sorry if this isn’t right :(

hope this is exactly what u need
The arc subtends an angle of 300° .
Step-by-step explanation:
Radius = 75 cm
Arc length = 125π cm
Arc length = (θ/360) (2πr)
125π = (θ/360) (2π x 75)
125π = (θ/360) (150π)
125π/150π = (θ/360)
5/6 = (θ/360)
(5/6) (360) = θ
θ = 300°
The arc subtends an angle of 300° .
