Answer:
a=2 and b=2...............
⅔ - ½ = 4/6 - 3/6 (make denomenator the same)
= 1/6
Thus, 1/6 = 40 litres
A full tank is 6/6 which equals to 1 whole
So,
1 unit (from 1/6) = 40 litres
6 units (from 6/6) = 40 × 6
= 240 litres
Therefore, the tank holds 240 litres when it is full.
( i hope my solution helps :3 )
The equation for finding the area of a circle of A=pi(r^2). Just plug in r=4 to find the area:
A=pi(4^2)
A=16pi
A=50.27 units squared
