Answer:
≈ 3927 litres
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = Ah ( A is the area of the base and h the height )
Note that h of oil = 250 ÷ 2 = 125 cm ( since half full )
V = πr²h
= π × 100² × 125 = 1250000π cm³ ( divide by 1000 )
= 
= 1250π litres ≈ 3927 litres ( to the nearest litre )
4^x=2×2^x=2×7=14
4^x-1=14-1=13
Answer:
(2,0) and (2,3)
Step-by-step explanation:
Answer:
He needs to gain more than 26 yards in order to break his record
Step-by-step explanation:
Let y stand for the number of yards he’ll have to gain. The sum of y plus the number of yards he already has (203) must be greater than 229 in order for him to break the record.
203 + y > 229 Set up the inequality.
203 − 203 + y > 229 − 203 Subtract 203 from both sides of the inequality.
y > 26
The formula for volume of a cylinder is 3.14r^2h.
r = 3
h = 6
3.14 x 3^2 x 6
3.14 x 9 x 6
=169.56
