Since x & y vary directly (it means when x increases, y increases & vice versa)
Then the equation==> y = k.x (k is a constant to be calculated)
But x=4 and y= (given) ==> 2=4k or k= 1/2 & the equation becomes <span>y=1/2 (x)</span>
Answer:
12.9
Step-by-step explanation:
AB = =
BC = =
CD = =
DE = 3
EA = =
The sum of all of these (in decimal form) is (approx.) 12.9
The formula for finding the Volume of square pyramid is given by :
where a is base edge and,
h = height.
We are given in the figure,
base edge = 18cm
Height =12 cm
So plugging these values in the formula for volume , we have
On solving we get ,
Volume of square pyramid = 1296 cm³.
So first option is the correct choice .
