Answer:
Slope=− 2.0000.500=−0.250
m−intercept= 1/9 =9.00000
n−intercept= 4/9 =2.25000
Step-by-step explanation:
47.098 rounded to the nearest tenth is 47.1
So this means they just fliped the numbers around
Answer:
Hence when the radius is halved the area is divided by 4
2.5 inches^2
Step-by-step explanation:
Given data
Area= 10inches^2
We know that the expression for the area of a circle is given as
Area= πr^2
10= 3.142*r^2
10/3.142= r^2
r^2= 3.18
Square both sides
r= √3.18
r= 1.78 inches
Now let us half the radius and find the area of the new circle
r/2= 1.78/2
r= 0.89
Area of the new circle is
Area= 3.142*0.89^2
Area= 3.142*0.7921
Area= 2.5 inches^2
