Answer:
90π in^3.
Step-by-step explanation:
Total Volume = volume of cylinder + volume of the hemisphere.
= πr^2h + 1/2*4/3πr^3
= π * 3^2 * 8 + 2/3 π 3^3 ( Note the radius r = 1/2 diameter = 1/2*6 = 3)
= 72π + 18π
= 90π in^3.

Answer:
Option D: The area will be multiplied by 16.
Step-by-step explanation:
Given that the area of the figure is 13 sq. in.
Let is say the figure is of dimensions: a & b.
Therefore, a.b = 13 sq. in
When each of the dimension is multiplied by 4, the dimensions would become 4a and 4b.
Therefore, the area would be: 4a . 4b = 16 a . b = 16(13) sq. in.
Hence, the area is multiplied by 16.
