Answer:
452.2 cm
Step-by-step explanation:
A = 4πr²
A = 4 (3.14) (6)²
A = 4 (3.14) (36)
A = 452.16
A = 452.2 cm (nearest tenth)
An easy way to find it (aka the avarage) is to add the two numbers together and divide the result by 2 so
15+37=52
52/2=26
another way is to subtract 15 from 37 and divide the result by 2, then you add this to the smaller number so
37-15=22
22/2=11
15+11=26
also
37-11=26
