Answer:
Step-by-step explanation:
The shape consists of three parts: a half sphere, a round cylinder and a round cone.
The half sphere volume = 1/2 * 4/3 * π * (4)^3
= 32/3 π
The round cyllinder volume = π * (4)^2 * 10
= 160 π
The round cone volume = 1/3 * π * (4)^2 * 3
= 16 π
Adding them together, the volume of shape
= 32/3 π + 160π + 16π
= (32/3 + 160 + 16)*3.14
= 586.13
Similarly the surface area
= (4π4^2)/2 + 2π4*10 + π*4*5
= (32+80+25)*3.14
= 430.18
The other 6 books can be arranged in 6 ways
= 6*5*4*3*2*1 = 720 ways answer
a12 * p78 = 936ap
Is that the answer u needed?
Hope it is... & Hope it helps

Look at your picture
notice the coordinates for the center of the circle, the x,y or h,k values
notice how long the radius is
thus
