Acylinder has a radius of 22 cm and a height of 7 cm. what is the exact surface area?

1276π cm^2

Step-by-step explanation:

2(π*22*22) + 2(π*22)7  

968π+308π = 1276π cm^2

0.82

Step-by-step explanation:

Step 1: (Calculating mean)

=>

=>

=> Mean = 6

Step 2:

=> (5-6)² = (-1)² = 1

=> (6-6)² = (0)² = 0

=> (7-6)² = (1)² = 1

Step 3: (Adding all values calculated in step 2)

=> 1+ 0 + 1 = 2

Step 4: (Dividing the result in step 3 by no. of observations)

=> 2/3 = 0.67

Step 5: (Get square root to calculate the deviation.)

=> = 0.82
