Answer:
C and E
Step-by-step explanation:
We are given that
A.
Hence, it is not in proportional relationship with (0.2,0.3)
B.(2.7,4.3)
Hence, it is not in proportional relationship with (0.2,0.3).
C.(3.2,4.8)
Hence, the ordered pair (3.2,4.8) are in a proportional relationship with (0.2,0.3).
D.(3.5,5.3)
Hence, the ordered pair (3.5,5.3) are not in a proportional relationship with (0.2,0.3).
E.(5.2,7.8)
Hence, the ordered pair (5.2,7.8) are in a proportional relationship with (0.2,0.3).
In order to get how much is being covered, we need to know the formula of the area of a circle.
Area = pi * r^2
Area = pi * (16/2)^2
Area = pi * 8^2
Area = pi * 64
Area = 200.96 in^2
So the correct answer is letter B. 200.96 in^2

</span>Given numbers:
74 % of 315
89% of 195
now, let’s solve the first given numbers:
=> 74% of 315
=> 315 is the 100%
Let’s convert 74% into decimals
=> 74% = .74
=> 315 * .74 = 233.1, the value of 74% of 315
Let’s solve the second given:
=> 89% of 195
where 195 is the 100%
=> 89% = .89
=> 195 * .89
=> 173.55, the value of 89% of 195</span>
