Answer:hope it helps
Step-by-step explanation:
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·3.5·(3.5+15.52+3.52)≈213.20692cm²

Answer:
pls mark me as brainliast
Step-by-step explanation:
Right circular cone
Solve for surface area
A≈213.21cm²
r Radius
3.5
cm
h Height
15.5
cm
r
Using the formulas
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·3.5·(3.5+15.52+3.52)≈213.20692cm²
