Find the area of a circle whose radius is 3½m​

38.48m squared

Step-by-step explanation:

Area = pi x radius squared

So

3.5 squared is 12.25

12.25 x pi is 38.48

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
