Hey there!!

  • The area of a circle = πr²

The area is given as 196π

Hence,

196π = πr²

... r²= 196

... r = √196

... r = 14

<em>Hence, the radius is 14 cm. </em>

<em>Hope it helps!</em>

Answer:


Step-by-step explanation:

The area formula for a circle is A = pi*r^2.  Solve this for the radius (raio):

r^2 = A / pi, or r = plus or minus √(A/pi).

Here, r =  +√(A/pi) = +√( 196 pi cm^2   /   pi ) = +7.9 cm.

Check:  A = pi*r^2.  Does pi*(7.9 cm)^2 = pi*196 cm^2?   Yes.

What is 26.5 rounded to the nearest hundredth??
blagie [28]
Remember your Number system
After the decimal point to the right, the next digit is the TENTH, and next is HUNDREDTH.

So for 26.5   =  26.500.
The tenth digit is 5, and the Hundredth is 0.
After the hundredth digit which is 0, the next digit is also 0.
The second 0 is not up to 5, so we would not add to the first zero.
(Was it 5, or above, we would have added 1 to first zero)

So the answer is 26.50.  If the next digit after the hundredth digit was 5 or more the answer would have been 26.51.

But for this question the answer is 26.50 to the nearest hundredth.  Cheers.
