What is the surface area of a cylinder that is 5 centimeters high and has a diameter of 1.5 centimeters?
A. 7.5π cm^2
B. 8.625π cm^2
C. 10.5 π cm^2
D. 19.55π cm^2

The surface area of cylinder is 8.625, if the cylinder has 5 centimeters high and 1.5 cm of diameter.

Step-by-step explanation:

The given is,

          Cylinder has a 5 centimeters height

          Diameter of the cylinder is 1.5 centimeters

Step:1

          Formula for the surface area of cylinder is,

                     ......................................(1)

          Where,

                   h - Height of cylinder

                   r - Radius of cylinder

        From the values of h and r,

                      =

                   r  = 0.75 cm

       From the formula,

                      = ( 2 × × 0.75 × 5 ) + ( 2 × × )

                      = ( 7.5 ) + ( 1.125 )

                  A = 8.625

Result:

        The surface area of cylinder is 8.625, if the cylinder has 5 centimeters high and 1.5 cm of diameter.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
