Answer:

i believe its 9.09

Step-by-step explanation:

i did this problem 3 different ways

first i put it all in a calculator and got 9.09

then i did 0.81/0.09 = 9+ 0.81 = 9.81/9 = 1.09

finally i did 0.81/0.09 = 9 0.81/9 = 0.09

9+ 0.09 = 9.09

therefore 9.09 is what i believe the answer is

i hope this helps you!

The area of a circle is 43.25cm2.<br> Find the length of the radius rounded to 2 DP.

Monica [59]

Answer:

3.71 cm

Step-by-step explanation:

Hi there!

Area of a circle equation: $A=\pi r^2$ where r is the radius

Plug in the area 43.25 cm²

$43.25=\pi r^2$

Divide both sides by π to isolate r²

$\frac{43.25}{\pi} =\frac{\pi r^2}{\pi} \\\frac{43.25}{\pi}=r^2$

Take the square root of both sides to isolate r

$\sqrt{\frac{43.25}{\pi}} =r\\3.71=r$

Therefore, the length of the radius rounded to 2 decimal points is 3.71 cm.

I hope this helps!
