Answer: 2 times 9 plus 10
Step-by-step explanation
2 times 9 equals 18 and 18 plus 10 = 28
Answer:
The volume of cone = Maximum holding of glass = 60 cube cm(cm^3)
Step-by-step explanation:
Cone formula:
The radius is 3cm and Volume is 60cm^3.
if pi =~ 3 So the "h" is 6.66 cm.
"h" is distance from cone's head to its base.
The "H"( height of glass) = 6.66 + 7 = 13.6 =~ 14
Answer:
1/2
Step-by-step explanation:
Dividing by 2 is the same as multiplying by 1/2.
The ratio between two numbers can be represented as a fraction.
We can take any two consecutive numbers to find the ratio.
-760/-380=1/2
-380/-190=1/2
The ratio will always be the same no matter which numbers you use.
I think the answers are 2/6 ,3/9, 4/12, 5/15.
