Answer:
x =5
Step-by-step explanation:
Distribute the 7
leaves you with 14x - 28 =42
Add 42 to both sides, cancelling out the 28 on the left
left with 14x = 70
70/14 = 5
x = 5
Alright so
5^4m = 5^12
cancel the bases
4m=12
divide by 4
m=3
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 :
