Formula:
Shape = Cone
Radius (R) = 1
Height (H) = 4
Formula of surface area (cone) = A=πr(r+h2+r2)
How to find a surface area of a cone?
Using the formula of the cone (A=πrl+πr2) We add the formula so the radius and the height (l=r2+h2). Since we are solving for a our formula will end up looking like (A=πr(r+h2+r2)=π·1·(1+42+12)≈16.09471). Which will equal our answer which is 16.09471. Round to the nearest tenth will be 16.09.
Answer: 16.09
