854.08 unit²

Step-by-step explanation:

Find the surface area of the hemisphere on top:

surface area = 2πr²

surface area =  2π(8 ÷ 2)² = 32π unit²

Find the surface area of the curved surface of the cylinder:

surface area = 2πrh

surface area = 2π(8 ÷ 2)(8) = 64π unit²

Find the surface area of the hemisphere on the bottom:

curved surface =  2πr²

curved surface =  2π(16 ÷ 2)² = 128π unit²

top surface = πr₁²  - πr₂²

top surface = π(16 ÷ 2)²  - π(8 ÷ 2)² = 48π unit²

surface area = 128π + 48π = 176π unit²

Find total surface area:

Total surface area = 32π + 64π + 176π = 272π = 854.08 unit²

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
