Answer:
"13.48 Kwhr" is the right solution.
Explanation:
The given values are:
Average rate of heat energy,
= 0.063 W/m²
Diameter,
= 8m
Efficiency of conversion,
= 50%
Now,
The area of hotspot will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
Total heat generation rate will be:
⇒ 


hence,
The electricity generation capacity will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
On converting into Kwhr, we get
⇒
