Answer:
radius = 5
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here r² = 25 ( take the square root of both sides )
r =
= 5
The number of small tiles are needed is 300 tiles.
<h3>Number of tiles needed</h3>
Using area of rectangular formula
Area of the room = length(l) × breadth (b)
Area of the room=300 cm×180 cm
Area of the room=54,000 cm²
Number of tiles needed = Area of rectangular region / Area of one tile
Number of tiles needed=54,000/180
Number of tiles needed=300 tiles
Therefore the number of small tiles are needed is 300 tiles.

To solve the inequality:
![-6](https://tex.z-dn.net/?f=-6%3C5t-1%3C0)
Add 1 to the sides of the inequality:
![-6+1](https://tex.z-dn.net/?f=-6%2B1%3C5t-1%2B1%3C0%2B1%5CRightarrow-5%3C5t%2B0%3C1)
Then
