Answer:
Step-by-step explanation:
volume = volume of cone + volume of hemesphere
= 1/3* pie* R^2 *h + 2/3 *pie* R^3 radius of cone = 7 cm = 1/3 pie* R^2 [ h +2R] height of cone = 10cm
= 1/3 *22/7*7*7 [ 10 +14] radius of hemesphere = 7cm
= 1/3*22 * 7 [ 24]
= 22 * 7* 6
= 924 cm ^3
now the area of the sheet =
pie * R * L + 2* pie * R^2 L = √ h^2 = R ^2
L = √149= 12.2cm
=22/7 * 7 *12.2 + 2 * 22/7 * 7 * 7
= 583 cm^2
thank you
