Im not for sure on this but i would say DF is 13
Answer:
The height of right circular cone is h = 15.416 cm
Step-by-step explanation:
The formula used to calculate lateral surface area of right circular cone is: 
where r is radius and h is height.
We are given:
Lateral surface area s = 236.64 cm²
Radius r = 4.75 cm
We need to find height of right circular cone.
Putting values in the formula and finding height:

So, the height of right circular cone is h = 15.416 cm
I don't get it. Does your score go down 8 points four times?
4(a+4)−2=34
Simplify:
4(a+4)−2=34
(4)(a)+(4)(4)+−2=34(Distribute)
4a+16+−2=34
(4a)+(16+−2)=34(Combine Like Terms)
4a+14=34
Subtract 14 from both sides.
4a+14−14=34−14
4a=20
Divide both sides by 4.
4a/4=20/4
a=5
