The formula is 1/2 x ( a + b ) x h
A and b are the top and bottom sides and h is always the perpendicular height.
Now replace the variables...
1/2 x (6 + 14 ) x 8.4
And then...
1/2 x 20 x 8.4 which will give you 84cm^2
Hope this helps! Anymore questions let me know :)
Y=2x and y = x² - 3. To find the intersections of these 2 functions we proceed as follows:
2x= x²-3 → x² - 2x -3 =0
The zeros of this trinomial are x = 3 and x =-1
Now to find y-coordinates replace in any of the initial equation x by both values:
y = 2x . For x = 3 , y = 6
and for a = -1, y = -2
Answer:
x-4,y-3
Step-by-step explanation:
left = negative , down = negative
The height of the right cone given its volume and its diameter is 47 units.
<h3>What is the height?</h3>
A cone is a three-dimensional object that has a circular base and a vertex.
Height of the cone = Volume of a cone ÷ 1/3(πr²)
Where:
- π = 22/7
- r = radius = diameter / 2 = 30 / 2 = 15 units
- h = height
3525π÷ (1/3 x π x 15²) = 47 units
