Surface area =  PI x rL + PI x r^2

since the answer is in terms of PI, remove PI from the equation:

surface are = rl +r^2

r = 3 and l = 15

3*15 + 3^2 = 45 +9 = 54

answer is 54PI units^2

Answer is C

Point T is on line segment SU. Given ST=2x+6, TU=4, and SU=4x, determine the numerical length of ST.
serg [7]

The numerical length of ST is 16

<h3>How to determine the numerical length of ST?</h3>

The given parameters are:

ST = 2x + 6

TU = 4

SU = 4x

The above parameters can be represented as:

SU = ST + TU

This gives

4x = 2x + 6 + 4

Evaluate the like terms

2x = 10

Divide by 2

x= 5

Substitute x= 5 in ST = 2x + 6

ST = 2 * 5 + 6

Evaluate

ST = 16

Hence, the numerical length of ST is 16
