Oksanka [162]

The largest radius of the circle that can fit inside the given square is 1.25 meters

Step-by-step explanation:

Step 1 :

Given,

the side of the square  = 2.5 meters

We need to determine the largest radius of the circle that can fit inside this square

Step 2 :

The diameter of the largest circle that can fit inside a square will be equal to length of given square's side.

So here the largest diameter will be 2.5 meters

Therefore the radius  = diameter ÷ 2 = 2.5 ÷ 2 = 1.25 meters

Step 3 :

Answer :

The largest radius of the circle that can fit inside the given square is 1.25 meters

Solve for k.<br> 12/k = 3
hram777 [196]

Answer:

k=3/12

k=.25

Step-by-step explanation:

we need to get k by itself

because 12 is over k we need to get rid of it by moving it to the other side (multiplying) because it is 12/k we need to multiply it by 1/12

This eliminates 12 and leaves us with k=3/12
