I need to find surface area of a cylinder. Formula being used: S.A= L x W +

Mathematics

Arturiano [62]4 years ago

Answer:

90π yd²

Step-by-step explanation:

the surface area of a cylinder is the sum of the lateral area and twice the aera of one end of the cylinder:  π·d·l, where l represents the length of the cylinder.  Here, the lateral surface area is π·6 yd·12 yd, or 72π yd².

The two ends add the following to the total surface area:

2·π·(d/2)², or 2π·d²/4.

Thus, the total surface area of the cyl. is

A = 2π·(6 yd)²/4 + 72π yd², or

A = 18π yd² + 72π yd² = 90π yd²

Note:  Please check your source.  L x W +  2pi ·r ^2 is incorrect.

What two mixed numbers between 3 and 4 have a product of 9 and 12
dlinn [17]
It's a trick question. There are an infinite number of mixed numbers between 3 and 4 that can multiply to equal 12 (for example, 3 and 3/7 times 3 and 1/2), but there are no mixed numbers between 3 and 4 that can multiply to equal 9. 3 times 3 is not between them but is 3, but that quantity is excluded because 3<x<4. Anything even a small bit above the number 3 would have to be multiplied by 2 and some fraction, which would not be between 3 and 4.

What is the average rate of change of the function f(x)=4(2)^x from x = 0 to x = 2? Enter your answer in the box.
bekas [8.4K]

average rate of change is just the slope from (0,f(0)) to (2,f(2))


basically, average rate of change=slope=\frac{f(2)-f(0)}{2-0}

evalaute each

f(2)=4(2)^2=4(4)=16

f(0)=4(2)^0=4(1)=4


so average rate of change=\frac{16-4}{2-0}=\fracc{12}{2}=6

average rate of change is 6
