Let me give a similar example...the radius of a circle is 5cm. What is the area and circumference. Area = πr^2 = π5^2 = 25π. Circumference = 2 x π x 5 = 10π The value for π is 3.142 but since this is a 5th grade math sum, i doubt they'll want you to
Formula for area of a circle is πr^2 Formula for circumference is 2πr or πD where D is diameter which is double the radius. Now, try do the math...I will be glad to check your work.
let me give you an example with a similar problem... (x^2+5x+6)/(x+3) To do this, you have to first factorize the numerator: To factor the numerator, you first find the products of the constant (+6) that when added together will give you the coefficient of
You have to first factorise the numerator, then a term in the numerator will cancel out the (x-2) in d denominator.
