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 :
0.3*0.6 = 0.18. By definition of independent.
Answer:
A: X < 7
Step-by-step explanation:
x = Nick's age y = Sara's age
Nick is 8 years older than Sara, therefore
y = x - 8
Answer:
left
Step-by-step explanation:
The question says she used
of it, so she probably used
of it. I'm assuming this is an error in the question, and it should be asking how much is left. To solve for that:
- 
make denominators equal
