Step-by-step explanation:
because it is raising the price by making money by 54%. and that its using the calculator in any way.
X = 39ft
It’s the same units as house A it’s just a reflection
Area=pi times radius^2 so
if area=4pi=pi times r^2
4 times pi=r^2 times pi
divide both sdies by pi
4=r^2
square root
2=radius since legnth cannot be negative
radius=1/2 diamters
2 radius=diameter
2(2)=diameter=4
diameter=4
