50.24, 120.7, 254.34, 415.27, 25.5, 1.77

Step-by-step explanation:

The formula for finding the area of a circle is πr²:

In that case, we can substitute each value in each circle  as r.

Circle 1 (radius 4 cm.)

We first begin by squaring our 4. That gives an answer of 16. Now, we multiply by 3.14. Since 16 * 3.14 = 50.24. It asks for all answers to be rounded to the nearest hundredth, though. In that case, our answer still remains 50.24

Circle 2 (radius 6.2 in.)

We first begin by squaring our 6.2. That gives an answer of 38.44.  Since 38.44 * 3.14 gives an answer of 120.7016. Rounding gives 120.70.

Circle 3  (diameter 18 ft.)

We first begin by dividing 18 by 2. That is because the diameter is twice the radius. Now we have 9 squared which gives an answer of 81. 81 * 3.14 = 254.34. Thus, our answer is 254.34 because it cannot be rounded.

Circle 4 (radius 11.5 m.)

We first begin by squaring 11.5. That gives an answer of 132.25. Multiplying by 3.14 gives an answer of 415.265. Rounding gives 415.27.

Circle 5 (diameter 5.7 cm.)

We first begin by dividing 5.7 by 2. (note: this circle is like circle 3). That gives an answer of 2.85. 2.85^2 = 8.1225. Multiplying by 3.14 = 25.50465 . Rounding gives 25.50. Thus our answer is 25.50

Circle 6 (radius 0.75 in.)

We first begin by squaring 0.75. That gives an answer of 0.5625. Now, we multiply times 3.14. That gives an answer of 1.76625. Rounding gives 1.77 as our final answer.

Hope this helps!
