Answer: The age of the twins is 10 years.

Step-by-step explanation:

Suppose the age of older sister be x

Let the age of twins sister be x-9, as they are born after 9 years.

Product of their ages be

$x(x-9)(x-9)\\\\=x(x^2-18x+81)\\\\=x^3-18x^2+81x$

Sum of their ages will be

$x+x-9+x-9\\\\=3x-18$

According to question,

$1861+3x-18=x^3-18x^2+81x\\\\x^3-18x^2+81x-3x+18-1861=0\\\\x^3-18x^2+78x-1843=0\\\\x=19$

So, Age of older sister will be 19 years.

Age of the twins will be

$19-9=10\ years$

Hence, the age of the twins is 10 years.

You would divide 10 into 477 to get 47.7, but you can't put 47.7 because you can't have a decimal. The answer is 47

Circumference of a circle = 2pie*r
= 19.8=2*314*r/100
= 1980 = 628*r
r = 1980/628
r = 3.13
~= 3 cm^2

16 because the base is 8 and the height is 4. That equals 32. 32/2=16
