Since you already know the radius multiply it by itself(20*20=400)then multiply that amount by 3.14.(formula: 3.14*(radius*radius)
Here is number 7:

Here is number 8:

Use the quadratic formula to find the other two solutions:
So area of cake
area=pi times radius^2
diameter=2radius
diameter/2=radius
find radius
diameter=6
6/2=raidus=3
formula is
A=3.14 times 3^2
A=3.14 times 9
A=28.26 cm^2
Answer:
Translate figure A down 4 units and left 6 units, and dilate it by a scale factor of 3.
Step-by-step explanation:
is your answer
hope it helps you
Formular is (principal *time*rate )/100 +principal
so applying that we have( 2000*5*7) +2000 which gives 2700 dollarss
