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 .
Answer:
ok sure
Step-by-step explanation:
So 'mean' basically just means average, and to get the average you must first add together all of the measurements. Then you have to divide that number by how many measurements you have, and in this case that would be 4.
13 + 7 + 9 + 6 = 35
35 ÷ 4 = 8.75
So the answer to this question is 8.75
Answer:
4m² + 6mn - 2n²
Step-by-step explanation:
Answer:
x + y = -3.
Step-by-step explanation:
x + y = 2
y = -x + 2
- the slope of this line is -1 . The line parallel to it will also have a slope of -1.
It also passes through (-7,4) so we have
y - 4 = -1(x - -7)
y - 4 = -1(x + 7)
y - 4 = -x - 7
x + y = -3 is the required equation.
