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

Let's solve your equation step-by-step.
−7x=−2x2+15
Step 1: Subtract -2x^2+15 from both sides.
−7x−(−2x2+15)=−2x2+15−(−2x2+15)
2x2−7x−15=0
Step 2: Factor left side of equation.
(2x+3)(x−5)=0
Step 3: Set factors equal to 0.
2x+3=0 or x−5=0
x= or x=5
Answer:
x= or x=5
