Answer:
Area = 16π m²
Circumference = 8π m
Step-by-step explanation:
(please refer to attached.)
we are given that the diameter, D = 8m
hence the radius = D/2 = 8/2 = 4m
from the attached we can see that:
Area = πr²
If we substitute the value of r that we found above and π = 3.14 into the equation, we get:
Area = πr²
= π(4)²
= π(16)
= 16π m²
Similarly, for circumference
C = 2πr
= 2(π)(4)
= 8π m

Answer:
The Ratios are Proportional
Step-by-step explanation:
Let,
R1 = 48 / 72 ----- (1)
R2 = 6/9 ------ (2)
If we divide right hand side of above equation by 8, we get,
Therefore, it means that, in simplified form, both ratios are same and hence proportional.
R1 : R2 = 6/9 : 6/9
