Question

Please do number 10. Thanks.

Answer 1

Answer:

379.94

Step-by-step explanation:

area of a circle is pi*radius squared. Radius is 11. 11*11=121. Now all you have to do is multiply 3.14*121. 3.14*121=379.94

Answer 2

The equation for the area of the circle ⇒ $\pi r^2$

• r: length of the radius --> 11cm
• $\pi$ --> 3.14

Now lets plug in all the known values in the equation:

    $\pi r^2=3.14 * 11^2 = 3.14 * 121 = 379.94$

Thus it wants the answer rounded to the nearest whole number, so

   Answer: 380 square centimeters

Hope that helps!
