A coefficient is a number that is being multiplied by a variable. In this case, we see that x in one term is being multiplied by 4, and in another term, x is being multiplied by -16 (If you change the operation to addition, you negate the 16).

So the coefficients in this expression are: 4 and -16.

The area of a circle is 80.86cm2. Find the length of the radius rounded to 2 DP.

weeeeeb [17]

Answer:

Solution given:

The area of a circle =80.86cm²

we have:

The area of a circle =πr²

substituting value of area of circle we get

80.86cm=3.14*r²

dividing both side by 3.14

80.86/3.14=3.14*r²/3.14

25.75=r²

doing square root on both side

$\sqrt{25.75}=\sqrt{r²}$

r=5.07cm

The length of radius is 5.07cm
