Answer:
Step-by-step explanation:
<h2>Cone:</h2>
diameter = 12 cm
r = 12 ÷ 2 = 6 cm
h = 6 cm


To find the surface area, we need to find the slant 'l'


= 3.14 * 6 * (6 + 8.49)
= 3.14 * 6 * 14.49
= 273 cm²
Answer:
Assuming that you're calculating surface area it would be:
16+10+10+10+10 or B
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
Work backwards. If -2 x 2= -4 then something plus negative four will equal 16, which is 20.
Answer: |x-5|
Step-by-step explanation:
I dont know how to exlplain it
If you know the volume then:
(3 * Cone Volume) / (PI * radius^2) = height
