The formula for the surface area of a right cylinder is 2πrh + 2πr^2. r is the radius, and h is the height.
In this instance, the radius is 4, so plug that in for r. (I.E. Replace r with 4).
The formula is now 2π4h + 2π4^2.
Next, plug in the height, 8 for h.
Now we have 2π4(8) + 2π4^2, which is approximately 301.59.
The surface area is 301.59. (Unit of measure was not specified)

The weighted weekly mean of t-shirt sales is 5.6.
The total number of weeks reported is the sum of the frequency column.
1+4+7+3 = 15 weeks
The total number of t-shirts sold is calculated as the product of the quantity of t-shirts sold and the number of weeks during which those t-shirts were sold.
2*1 + 4*4 + 6*7 + 8*3 = 2 + 16 + 42 + 24 = 84
The weighted mean, which is the product of the total quantity of t-shirts and the total number of weeks, represents the average number of T-shirts sold every week:
84/15 = 5.6
Response: 5.6
