Answer:
Step-by-step explanation:
To solve an equation for one of its variables do that:
- Underline the variable
- Separate it one side and the other terms on the other side
- Make its coefficient equal to 1
Let us use these steps to solve our question
∵ V = πr²h
→ Underline r²
∴ V = π<u>r²</u>h
→ Take π and h to the other side by dividing both sides by πh
∵
∴
→ The coefficient of r² is 1, so switch the two sides
∴
Area of the square: 29.0
Step-by-step explanation:
The area of a square is given by
where
L is the length of the side of the square
The sides of a square all have the same length, so here we just need to find the length of one side.
The length of the side of the square here is the distance between two vertices, which can be calculated as
where
are the coordinates of the 1st vertex
are the coordinates of the 2nd vertex
By taking the two vertices (3,6) and (1,1), we find
Therefore, the area of the square is:
