# Calculate A

A = math.pi*r**2

# Build printout

# Create list baseball

# Import the numpy package as np

# Create a numpy array from baseball: np_baseball

# Print out type of np_baseball

print(type(np_baseball))

# baseball is available as a regular list of lists

# updated is available as 2D numpy array

# Import numpy package

import numpy as np

# Create np_baseball (3 cols)

np_baseball = np.array(baseball)

# Print out addition of np_baseball and updated

print(np_baseball + updated)

# Create numpy array: conversion

conversion = np.array([0.0254, 0.453592, 1])

# Print out product of np_baseball and conversion

print(np_baseball * conversion)

# heights and positions are available as lists

# Import numpy
