l=r2+h2
Solving forV
V=1
3πr2l2﹣r2=1
3·π·42·52﹣42≈50.26548cm³

Answer:
107.264 cm³
Step-by-step explanation:
The volume of the Right Circular Cone = 1/3 π r²h
height = √r² + h`²
h` = slant height
= √4² + 5²
= √16+25
= √41
= 1/3 π r²h
= 1/3 * 22/7 * 4 * 4 *√41
= 1/3 * 22/7 * 16 * √41
= 22/21 * 16 * √41
= 352/21 * √41
= 16.76 * 6.4
= 107.264 cm³
= 1.07264 m³
= 1072.64 l
