A. if u unfold a cylinder, it is a circle, a rectangle, and a circle.
Find the area of those
to find the area of the circle, you need the radius.:
14/2= 7
To find the area of a circle, it is 3.14*r^2
=3.14*49
= 1538.6
Now you have to multiply it by 2 because there are two circles: 3077.2
Now find the area of the rectangle:
To find the area, you have to have the height (20cm) and the width of the rectangle/the circumference of the circle.
To find the circumference: 2*3.14*r(7)
= 2*3.14*7
=43.96
Now that you have that, you can find the area
43.96*20
=879.2
Now you add both products together
879.2+ 3077.2
=3956.4cm^2
B. divide 3956.4 by 3
=$1318.8
C. volume of cylinder: 3.14*r(7)^2h(20)
calculate that you get
3077.2
Hope that helps, and please notify me if I am wrong.
By adding all of the numbers on the the outside lines
In order to combine radicals when you're adding or subtracting, 2 things have to be in place. First, the index has to be the same. We have all the indices as 4's (fourth roots), so we're good there. Second, the radicand also has to be the same. Right now, none of them are, so we need to try to simplify and see if they are the same, just well-hidden. The first one, can be simplified down to . We can pull out one of those 4 twos, and when we do that we have which simplifies even further to . The second term, cannot be simplified at all...it is what it is. Next term, can be rewritten as . We can pull out one of those 4 threes and simplify to which simplifies even further to . Lastly, we have . We can rewrite this as . Pulling out 4 twos leaves us with which simplifies to . So here's what we have in all: . We will combine the like terms to get a final answer of . Third choice down is the one you want.
Answer: a) 24 b) infini
Step-by-step explanation: a) parce que tu peut faire que 24 somme pour faire 23. B) infini car tout plus haut 100 fonctione
9) The True Distance is 209 ft
10) The True Distance is; 66.5 ft
11) The True Height is; 57 ft
<h3>How to Interpret the Scale of a Map?</h3>
We are given that the scale of the map is 1 in : 38 ft
This means that 1 inch represents 38 ft
9) Now, we want to find the true distance of 5.5 inches from the map. Thus;
True distance = (5.5 * 38)/1
True Distance = 209 ft
10) Now, we want to find the true distance of 1.75 inches from the map. Thus;
True distance = (1.75 * 38)/1
True Distance = 66.5 ft
11) We are given the scale is 1 in : 85 ft.
Thus, the true height of 1.5 inches is;
True height = (1.5 * 38)/1
True Height = 57 ft
