Answer:
41cm
Step-by-step explanation:
The circumference of a circle is 82π
Therefore r can be calculated as follows
2 × π × r= 82× π
2πr= 82π
r = 82π/2π
r= 41
Hence r is 41cm
Answer:
6root2 × 6root2
you have to use pythagoras
a²+b²=c²
c=12
12²=144
a²+b²=144
but it is a square so I'll just change a and b to x because it shows they are equal
x²+x²=144
2x²=144
x²=72
x=6root2
