Paladinen [302]

Answer:

The answer to your question is: A = 1627.35 in²

Step-by-step explanation:

Data

height = 30 in

radius = 7 in

A = ?

Lateral area

  A = 2πrh

  A = 2(3.1416)(7)(30) = 1319.47 in²

Area of the base and lid

 A = 2 x πr²   = 2(3.1416)(7)²

                      = 307.88 in²

At = 1319.47 in² + 307.88 in²  = 1627.35 in²

hjlf

Answer:

P odd number, then 20) = 1 /14

Step-by-step explanation:

P( odd number) =  number of odd numbers/ total

number of odd numbers = 3

total = 7

P( odd number)   = 3/7

We keep the tile so that there are only 6 tiles left

P (20) = number of 20/ total

          = 1/6

We multiply the probabilities together

P odd number, then 20) = 3/7 * 1/6 = 3/42 = 1 /14
