Surface Area = 2πrh
If the h, is now h/3 and the r, now r/3
Surface Area = <span>2π*r/3*h/3
= </span><span>2πrh/9

Answer:
52 feet
Step-by-step explanation:
This situation can be represented by the attached figure as in the answer area.
Let M be the location of Mary.
Let S be the location of Sue.
Distance between apartments is given as 20 feet.
Distance between ground and balcony of Mary is 40 feet.
There is a right angled
.

To find:
The distance SO + 40 feet.
We can use tangent ratio here in right angled
.


Height of Sue above ground = 40+12 = <em>52 feet</em>
4096 kittens means 16,384 kitten legs. 512 cats = 2048 legs, 8 girls = 16 legs. So, 18,440 legs total.
