Question

tje base area of cone is 616cm^2 and height is 48cm then the total surface area is​

Answer 1

Answer:

Step-by-step explanation:

Given the area of base =  616

π r²  =  616

$\frac{22}{7}$ × r² = 616

r² =  616  ×  $\frac{7}{22}$

r²  =  196

r =  14

For the Total Surface Area,

A =  πr² + πr(√h² + r²)

=    616  +  $\frac{22}{7}$  ×  14  (√48²  +  14²)

=  616 + 44  ( √ 2304 + 196)

=   616  +  44 ( √ 2500)

=  616 +  44(50)  

=616 + 2200

A =  2816
