Kylie drew a circle with a diameter of 8 cm. paige drew a circle with a radius of 3 cm. approximately how much larger is the area of kylie’s circle than the area of paige’s circle? use 3.14 for pi and round to the nearest whole number.

22 sq. cm.

Step-by-step explanation:

Area of a circle is

where, r is radius of the circle.

Diameter of Kylie's circle = 8 cm

Radius of Kylie's circle = 8/2 = 4 cm

Radius of Paige's circle = 3 cm

Area of Kylie's circle is

Area of Paige's circle is

Difference between the areas is

Therefore, the area of Kylie’s circle is 22 sq. cm larger than the area of Paige’s circle.

understand that i don't know the answers

will someone answer his question

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
