Answer 2

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
