Question

PLEASE HELP ME!!! I REALLY NEED YOU TO HELP ME NOW!!!! THANKS!

Answer 1

Answer:

Surface of a Cylinder Code:

#import math package to use math.pi for the value of PI

import math

#take radius of the base of a cylinder from user

r=float(input("Enter r of a cylinder"))

#take height of the curve surface of a cylinder from user

h=float(input("Enter the Height of a cylinder"))

#calculate the surface area of cylinder

s_area=2*math.pi*pow(r,2)*h

#calculate the volume of cylinder

volume=math.pi*pow(r,2)*h

print("surface area of a cylinder wll be %.2f" %s_area)

print("volume of a cylinder will be %.2f" %volume)

Quadratic Equation Code:

import math

a = int(input("Enter the coefficients of a: "))

b = int(input("Enter the coefficients of b: "))

c = int(input("Enter the coefficients of c: "))

d = b**2-4*a*c # discriminant

if d < 0:

print ("This equation has no real solution")

elif d == 0:

x = (-b+math.sqrt(b**2-4*a*c))/2*a

print ("This equation has one solutions: "), x

else:

x1 = (-b+math.sqrt((b**2)-(4*(a*c))))/(2*a)

x2 = (-b-math.sqrt((b**2)-(4*(a*c))))/(2*a)

print ("This equation has two solutions: ", x1, " or", x2)
