calculate the perimeter of a triangle that has an area of 2340 cm2, and an in-circle with radius of 18cm.
1 answer:
Half of the perimeter multiplied by the radius of the inscribed circle is formula to find the area of a triangle, by using this you can see that the perimeter is 260 because 2340 / 9 = 260.

Answer:
Step-by-step explanation:
The equation of the circle with center A=(a,b) and radius = r are:
When A=(3,-2) and radius=r=-5
F(x) = x4(x2 - 1)
The expressions is undefined in the set of the real numbers.
add 2 to both sides
square both sides
3x-5=4
add 5 to both sides
3x=9
divide 3
x=3
a nswer is B
