Explain his error
The question says 5/8
Instead, Alejandro's working shows 8/5.
This working is done in an incorrect order and the correct solution is:
Let
Solve the fraction
Multiply by 100%
<em>Hence, option (a) is correct.</em>
Question 10: P=28cm
if l=8 and w=6
Then (8+6)=14
2(14) so 14x2 = 28
So therefore P=28cm
<h3>Answer:</h3>
x = 2
<h3>Explanation:</h3>
The rule for secants is that the product of segment lengths (on the same line) from the point of intersection to the points on the circle is a constant for any given point of intersection. Here, that means ...
... 3×(3+5) = 4×(4+x)
... 6 = 4+x . . . . divide by 4
... 2 = x . . . . . . subtract 4
_____
<em>Comment on this secant relationship</em>
Expressed in this way, the relationship is true whether the point of intersection is inside the circle or outside.
Answer:
Diameter of tank = 19.5 ft
Step-by-step explanation:
Volume of cylinder = Base area x Height.
Base area = Area of circle
Height = 20 ft.
Volume of tank = 6000 cubic feet .
Diameter of tank = 19.5 ft
