Answer:
AC=
Step-by-step explanation:
AC is the base, BC is the hypotenuse, so the side length is AB.
We are given that AC=7 units, and BC is equal to 8.
Thus we have 8^2-7^2=(AB)^2
64-49=(AC)^2
15=(AC)^2
AC=
It is C because 4 pi r^2 is the surface area equation. 4 times 6 squared= 144. 144pi = surface area.
Answer:
28043.3 
Step-by-step explanation:
Formula for volume of a hemisphere can be termed as:

where
is the radius of hemisphere
Please refer to the figure attached for the sample figure of a hemisphere.
We are given here, diameter of hemisphere = 47.5 m
Relation between diameter and radius is given as :

where,
is the radius and
is the diameter.
So, 
Volume is:

Hence, volume of given hemisphere is 28043.3

What I do personally is that I count the number of zeros in the number and that is how many powers the ten powers to. Like a, there are two zeros in 100 so its 10 to the power of 2.
