Find the surface area of the cylinder in terms of pi

A≈1639.91

Step-by-step explanation:

Shape: Cylinder

Solved for surface area

Radius: 9

Height: 20

Total surface area formula: =2πrh+2πr2

R is the radius

H is the height

So for this question H is 20 and R is 9in

A≈1639.91

Hope this helps.

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
