For the lateral area, don't include the base area. For the surface area, you should include it.
200+30 but its hard to understand what you are trying to say so please be more specific
The volume of the igloo is 523.43 m^3
<h3>
</h3><h3>
How to get the volume of the igloo?</h3>
We know that the volume of a sphere of radius R is:

Where pi = 3.14
Then the volume of a hemisphere is half of that.
In this case, we have a hemisphere with a radius of 6.3m, then the volume will be:

Answer:

Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation y=-23x+5. We will chose point-slope since we have a point and slope.
Point slope:
in our new equation because it us perpendicular to it. This means we will need to change it into its negative reciprocal which is
.
We will substitute
and
.
.
This is the equation of the line perpendicular to y=-23x+5 that crosses through (8,1).
Answer:
x = -7
Step-by-step explanation:
2x+2-x+5=0
x+2+5=0
x+7=0
x = -7
So the answer is -7
