Many artists incorporate geometric shapes into their art. An artist wants to make a sculpture shaped like a cone with a height o
f 4.2 inches and a radius of 2.5 inches. The artist needs to know the volume of the sculpture to purchase the correct amount of materials.
Part A. Which equation shows the art is used to calculate the volume of a cone with the given measurements
Part B. What is the volume,in cubic inches,of the cone? Use 3.14 for pie and round your answer to the nearest tenth

So what you do is
make into ax^2+bx+c=0 form
add-9/2 to both sides
y^2-2y+9/2=0
now we use the quadratice formula which is
x=
ax^2+bx+c=0
1y^2-2y+9/2
a=1
b=-2
c=9/2
subsitute
