Answer:
V =πr^3
Step-by-step explanation:
The height of the pyramid is 3 times the radius of the cone. So we can express height of the pyramid as a function of radius of the cone.
Let's take radius of cone = r
So, the height of the pyramid = 3r
Area of the base of the cone = πr^2 = area of the pyramid.
If the base dimensions of the pyramid are l and b, then area of the pyramid, l x b = π r^2.
The volume of the pyramid = 1/3 x l x b x h
We know, l x b =π r^2 and h = 3r.
Thus, volume of pyramid is = 1/3 x π x r^2 x 3 r
= π r^3.
Thank you.
Answer:
<h2> 8.06ft</h2>
Step-by-step explanation:
step one:
This problem is on the mensuration of solids,
given that the area is 65ft^2
step two:
we know that the expression for the area of a solid is
areaa= length* length
area= l^2
step three:
substituting the value of the area into the expression we have
65=l^2
we need to square both sides to solve for l we have
√65=l
l= 8.05ft
step four:
From the analysis we found the length of one side to be 8.06ft
Answer:
328
Step-by-step explanation:
(4x − 16)^½ = 36
Square both sides:
4x − 16 = 36²
4x − 16 = 1296
Solve for x:
4x = 1312
x = 328
