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:
53
Step-by-step explanation:
Given: The sum of two digit number is 8
Reversing the digit will get us number 18 less than the original.
Lets take x as tenth digit of our number and y as unit digit of our number.
As given sum of digit is 8
∴
∴ - equation 1
We also know that reversing the digit will get us number 18 less than the original.
∴
Now, lets put the value of y from equation 1
⇒
⇒
⇒
∴
Next, substituting the value of x in equation 1
⇒
∴
∴ The original number is 53, sum of the digit is 8 and if we reverse the digit of the number, we get 35, which is 18 less than the original number.
