Answer:
triangle; area = 90 ft2
Step-by-step explanation:
THe type of two dimensional solid created by a vertical cross section of the cone that passes through the apex is a triangle, as you can see in the picture, if you draw a line that cuts the cone in half passing through the apex it would just be a triangle, and the area of the cross section is given by the formula:
Since you have the radius of the base of the cone, you need the diameter to calculate the area, the diameter is given by the next formula:
Now you just put your values into the formula of the triangle:
So the area of the triangle formed is:
Answer:
$99
Step-by-step explanation:
MP3 Player: $100
10% Mark up: $100/10= 10
Therefore, Mark-Up Price: $100+$10= $110
This was then Marked down by 10%.
Therefore,
10% Marked down: $110/10= $11
(We then take this away from the marked up price)
Hence, Final Price : $110-$11= $99
You move the decimal point two places to the left when converting percentages to decimals.
0.613
0.4 / 2 = 0.2
1/0.2 = 5
2/5 is the answer
