Answer 1

Answer:

here is your answer dude

Step-by-step explanation

Consider r as the radius of the cone

It is given that  

Slant height of the cone =14 cm

Curved surface area of the cone =308 cm  

2

 

It can be written as

πrl=308

By substituting the values

7

22

​  

×r×14=308

On further calculation

22×r×2=308

So we get

r=  

2

308

​  

2×2)

r=7 cm

We know that

Total surface area of a cone =πrl(1+r)

By substituting the values

Total surface area of cone =  

7

22

​  

×7×(14+7)

On further calculation

Total surface area of a cone =22×21=462 cm  

2

 

Therefore, the base radius of the cone is 7 cm and the total surface area is 462 cm
