Answer:
Step-by-step explanation:
The surface area of a cylinder is given as;
where r = radius
h = height
The cylinder has a height of 32 feet and a diameter of 40 feet. This means that the radius is:
40 / 2 = 20 feet
The surface area is therefore:
The surface area of the cylinder is .

Clocks can display up to the number 59 (60 minutes in an hour). If you list all of the perfect squares that are under 59, you will find that there is 7 of them: 1, 4, 9, 16, 25, 36, and 49.
About $73.05 or $73; multiply .335 with $54.72 then add that answer to $54.72
The correct answer is A.) Obtuse.
When an angle is over 90° it is considered an obtuse angle. Any angle that measures under 90 is an acute angle.
The given statement is true.
Step-by-step explanation:
Given sets are:
D = {x|x is a whole number}
E = {x|x is a perfect square between 1 and 9}
F = {x|x is an even number greater than or equal to 2 and less than 9}
as the sets are given in set builder notation,, we will first write the sets in set notation.
So,
D = {0,1,2,3,4,...}
E = {4,9}
F = {2,4,6,8}
Now,
EUF = {4,9} U {2,4,6,8}
= {2,4,6,8}
Hence,
The given statement is true.
