Answer:
Step-by-step explanation:
Given:
To solve the expression, equating it to zero to write it in standard form.
Taking the terms of 'x' to one side and the constants to other side:
On simplification of the expression the value of 'x' is
ANSWER :
Surface area of larger cone : 24π units^2
Surface area of smaller cone : 6π units^2
The surface area of the smaller cone is 25% of that of the larger cone.
EXPLANATION :
From the given problem,
AB = 3 is the radius of the larger cone and the slanted height is BC = 5
DE = 1.5 is the radius of the smaller cone and the slanted height is EC = 2.5
Recall the surface area of the cone :
where r = radius and L = slanted height.
For the larger cone, r = 3 and L = 5
For the smaller cone, r = 1.5 and L = 2.5
Comparing the surface areas :
The area of the smaller cone compared to the larger cone is :
6: 26/15 or 1 11/15
7: 7/18
8: 47/240
9: 191/224
10: 11/60
11: 81/200
Hope it helps!
