PLEASE HELP The total surface area, in square units, of a cylinder with a radius of r units and a height
of h units can be represented by the formula SA = 22 + 2trh.
The first term of the expression represents the total area of the 2 circular bases of the
cylinder, and the second term represents the lateral area of the cylinder.
In a certain cylinder, the radius is related to the height as shown in the expression
212? + 2x (x+3)
Which of the following statements could be true?
The radius of a cylinder is equal to x units, and the height of a cylinder is equal to x + 3 units.
The area of one of the bases of a cylinder can be represented by the expression ?
The height of a cylinder is 3 times the length of its radius.
The radius of a cylinder is 3 units less than its height.
The lateral area of a cylinder can be represented by the expression 272?.

Arectangle has a width of 5 cm and a length of 10 cm. if the width is increased by 3, how does the perimeter change?

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.

Acompany manufactures three types of cabinets. it makes 110 cabinets each week. in the first week, the sum of the number of type-1 cabinets and twice the number of type-2 cabinets produced was 10 more than the number of type-3 cabinets produced. the next week, the number of type-1 cabinets produced was three times more than in the first week, no type-2 cabinets were produced, and the number of type-3 cabinets produced was the same as in the previous week.
