Find the radius of the circle

1.5

Step-by-step explanation:

Step 1: find the semiperimeter, s, of the traingle.

Semiperimeter = ½(a + b + c)

Where:

a = 5

b = 5

c = 6

Plug in the values into the formula

s = ½(5 + 5 + 6) = ½(16) = 8

Step 2: Find the radius using the formula,

Plug in the values into the formula

Take the square root of both sides

Radius = 1.5

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
