This is quite simple, the radius is half of the diameter Knowing the diameter is 14 14 divided by 2 = 7.
Now for a circle here is the equation A = Area
A = <span>π r ^2 </span> So we have the radius being 7 but now it needs to be squared.
7 x 7 = 49.
So now our equation is.
A = <span>π 49 ^2 (Keep in mind ^2 is just squared) </span> Now this is the answer but we can get more technical by multiplying 49 times <span>π </span> Now <span>π equals roughly 3.14 </span> So we can do 49 x 3.14 cm Which this equals 153.86
Which rounding to the nearest tenth gets you:
153.9 cm is your area
I really do hope this helps! Brainliest is always appreciated if you feel its deserved!
