Answer:
The volume of basketball is 7216.5 cm³.
Explanation:
Given data:
Radius of ball = 12 cm
Volume of ball = ?
Solution:
We will apply the volume formula of sphere.
V = 4/3 ×π×r³
we know that,
π = 22/7
r = 12 cm
Now we will put the values in formula.
V = 4/3 × 3.14 × (12 cm)³
V = 4/3 × 3.14 ×1728 cm³
V = 7216.5 cm³
Thus, the volume of basketball is 7216.5 cm³.

The enthalpy change for the reaction 2K + S + K2S using the following thermochemical reactions is mathematically given as
dn=70.7kg
<h3>What is the enthalpy change for the reaction?</h3>
Generally, the equation for the Chemical reaction is mathematically given as
2k+s----->K2S
Therefore
KS+K----->K2S
Therefore
dn=dn1+dn2
dn=32.5+38.2
dn=70.7kg
In conclusion, the enthalpy change is
dn=70.7kg
