Answer: 376.8 cm^2
Step-by-step explanation:
The formula for the surface area of a cylinder is A = 2prh +2pr^2
When:
- A = surface area
- p = value of pi (3.14 in this case)
- r = radius (= 1/2 diameter)
- h = height
When we substitute our values, we get the equation
A = 2(3.14)(4)(11) + 2(3.14)(4^2)
Now, we just multiply, square, and add our numbers to find A
A = 2(3.14)(4)(11) + 2(3.14)(4^2)
A = 2(3.14)(44) + 2(3.14)(16)
A = (6.28)(44) + (6.28)(16)
A = 276.32 + 100.48
A = 376.80
Because the hundredths place is a 0, we don't need to round.
A = 376.8
The unit is in centimeters. Area, and surface area by extent, are written in cm^2 (centimeters squared)
A = 376. 8 cm^2
<h3>Final answer: A = 376.8 cm^2</h3>
Answer:
0ne mile
Step-by-step explanation:
First you get figure out that Tara must have 1/3 of the shells from the other two ratios. Then you learn that 76 is 1/3 of the shells, therefore there must be 76*3 or 228 shells total.
Answer: In order, the boxes are -9, 1, -9
Step-by-step explanation:
The vertex is the tip point of an absolute value function, which in this case is (-9,1).
The axis of symmetry is a symmetrical line through the fuction which goes through the vertex which would be x = -9.
Answer:
4b+8 = 20
---------------
4b = 20
-------------------
b = 5
Step-by-step explanation:
We need to solve for b in the following equation:
When we multiply each term by 2 the denominator cancels out:
Next, we subtract 8:
Final step, we isolate the variable. We cancel the multiplication on the left side when dividing by 4 on each term
