Answer:
Step-by-step explanation:
From your knowledge of multiplication tables, you know ...
48 = 6·8 = 3·2·2·2·2 = 3·2^4 . . . . a = 4
56 = 7·8 = 7·2·2·2 = 7·2^3 . . . . . . b = 3
Answer:20π
Step-by-step explanation:
equation of the circle
(x+3)² + (y-5)² = r²
now, (-9, -3) lies on it
So, (-9+3)² + (-3-5)² =r²
36+ 64 = r² =100
hence, r =10
So, circumference = 2πr = 20π
