I’ve attached a photo of the workings but the answer is 82
Step-by-step explanation:
Take the LCM of the denominators:
=> LCM = 18
=> -7/9 x 2/2 = -14/18
=> -4/9 x 2/2 = -8/18
=> 1/9 x 2/2 = 2/18
=> 1/2 x 9/9 = 9/18
When the number is negative, the greater the number, the smaller it is.
So, -14 is smaller than -8.
< = smaller than
=> -14/18 < -8/18 < 2/18 < 9/18
=> -7/9 < -4/9 < 1/9 < 1/2
There are 16 ounces in a pound, so you would multiply 16 and 3 to get your answer.
To solve the problem, get first the area of the circle and the square -
Circle -> Area = pi * r^2; r= radius
= 3.14 * 1.5^2m^2 (radius is 1/2 of diameter)
= 3.14 * 2.25m^2
= 7.065m^2 or 7.07m^2 when rounded-off
Square -> Area = a^2; a = side
= 3^2m^2
= 9m^2
You can now perform the subtraction process -
9.00m^2 - 7.07m^2 = 1.93m^2
Therefore, 1.93m^2 is the difference between the area of circle and square
