The correct option is 15 data items per minute.

Explanation:

We are given that the Antonio can input statistical data into his computer at the rate of 2 data items faster each half hour he works.

Also, we are told that Antonio starts at a work at 9.00 AM inputting data at a rate of 3 data items per minute.

We can express the given information in an equation as:

$K=x+2 \times y$

Where:

x is the starting speed and y is number of half hours between the given time.

Since we have to find at what rate will Antonio be inputting data into the computer by noon. Therefore, there will be 6 half-hours between 9.00 AM to Noon.

Therefore, the equation is:

$K=3+2 \times 6 =3+12=15$

Therefore, Antonio will be inputting data into the computer by lunchtime (noon) 15 data items per minute.

9. 78.5 m $^{2}$

10. 379.94 in $^{2}$

11. 132.665 m $^{2}$

12. 12.56 yd $^{2}$

13. 226.865 ft $^{2}$

14. 113.04 ft $^{2}$

15. 63.585 ft $^{2}$

16. 254.34 m $^{2}$

17. 50.24 cm $^{2}$

step-by-step explanation:

7. $\pi x 7^{2} = \pi * 49 = 153.86 ft^{2}$

8. $\pi * 2^{2} = \pi * 4 = 12.56 ft^{2}$

9. $\pi * 5^{2} = \pi * 25 = 78.5 m^{2}$

10. $\pi * 11^{2} = \pi * 121 = 379.94 in^{2}$

11. $\pi * 6.5^{2} = \pi * 42.25 = 132.665 m^{2}$

12. $\pi * 2^{2} = \pi * 4 = 12.56 yd^{2}$

13. $\pi * 8.5^{2} = \pi * 72.25 = 226.865 ft^{2}$

14. $(\pi /4) * 12^{2} = 0.785 * 144 = 113.04 ft^{2}$

15. $(\pi /4) * 9^{2} = 0.785 * 81 = 63.585 ft^{2}$

16. $(\pi /4) * 18^{2} = 0.785 * 324 = 254.34 m^{2}$

17. $(\pi /4) * 8^{2} = 0.785 * 62 = 50.24 cm^{2}$
