Answer:
The surface area of cone = 54π cm²
Step-by-step explanation:
Given ;
Radius = 3 cm
slant height = 15cm
The surface area of cone = πr ( r + l )
=> π × 3 ( 3 + 15)
=> π × 3 ( 18)
=> 54 π cm²
To know if they are proportional check to see if there is a number common to the relationship between the y and x to all the numbers:
10/2=5
15/3=5
20/4=5
25/5=5
There is a relationship of 5 and the 5 is multiplied to the x=boxes.
Yes, because the price is 5 times the number of boxes
165 -25 =140
140/7= 20.
20 hours
2.28 is the answer I got
first I divided 6 by 100
then multiplied that by 38 and that's how I got 2.28
2.7 gallons.
Since the tank is already 4/5 full, only 1/5 is needed to fill it completely. As 13.5 gallons represent 5/5 (the full tank), you can take 13.5 divided by 5 to find 1/5.
