The radius of the circular top is 4. 75
<h3>How to determine the value</h3>
The formula for surface area of a rectangle is given as;
Surface area = 2πrh
Given that;
- surface area = 388cm²
- height is 13cm
- radius is unknown
Let's substitute the values
388 = 2 × 3. 142 × 13r
388 = 81. 64r
Make 'r' the subject
r = 388/ 81. 64
r = 4. 75
Thus, the radius of the circular top is 4. 75

Step-by-step explanation:
Number of choices = 5C2 = 5 * 4 / (1 * 2) = 10.
Answer:
x=2
Step-by-step explanation:
x turns out to be 2...
It seems the function f(x) is 3/(x+4).
If the function is f(x) = 3 / (x + 4), a table could be
x f(x)
-8 -3/4
-7 -1
-6 -3/2
-5 -1
(-4 is no a valid input)
- 3 3
- 2 3/2
-1 1
0 3/4
1 3/5
2 3/6 = 1/2
3 3/7
4 3/8
If the function is f(x) = (3/x) + 4
Just substitute different values for x and obtain the respective outputs. In this case, x has to be different of o, i.e. 0 is not a valid input.
