Question:

Match each area to its corresponding radius or diameter of the circle.(All areas are approximate.)

Answers

he is correct

Step-by-step explanation:

The answer is B. 27.318

Step-by-step explanation:

The formula for the circumference is , where r is the radius of the circle. Because we know that the radius is half of the diameter, which we're given, we'll have to divide the diameter by 2 to get this. Our equation would then become . However, because we're dividing by 2 and multiplying by two, these two cancel each other out, so the equation for circumference may also be written as , where d is the diameter.

Now we solve (where pi is simplified to equal 3.14):

C=27.318 cm.

We know that
Area circle=pi*r²> r=√(A/pi)

case 1) 221.5584 square units area > r=√(221.5584/pi)=8.398 units
Diameter=2r> 2*8.4=16.8 units

case 2) 78.5 square units area> r=√(78.5/pi)=5 units
Diameter=2r> 2*5=10 units

case 3) 452.16 square units area > r=√(452.16/pi)=12 units
Diameter=2r> 2*12=24 units

case 4) 36.2984 square units area > r=√(36.2984/pi)=3.4 units
Diameter=2r> 2*3.4=6.8 units

case 5) 314 square units area > r=√(314/pi)=10 units
Diameter=2r> 2*10=20 units

case 6) 886.2336 square units > r=√(886.2336/pi)=16.8 units
Diameter=2r> 2*16.8=33.6 units
