A circular lawn with a diameter of 20 square feet will be planted with grass seed. How many square feet are on the lawn?

31.4 ft squared
125.6 ft squared
314 ft squared
1,256 ft squared

Answer:

314 ft squared

Step-by-step explanation:

A = πr^2 = π · 102 ≈ 314.15927

Answer:

314.159265359 ft squared or 314.16 ft squared rounded to the hundredths place. The closest result is option C.

Step-by-step explanation:

The formula for finding the area of a circle is A=π×r^2.

Step 1: Find the radius which is half of the diameter. In this case, the radius is 10 feet.

Step 2: Square the radius that you found. In this case, the number will be 100ft or 10^2.

Step 3: Multiple this number by π, or 3.14 if your teacher allows it. So in this case, 100×π=314.159265359 or 314.16 rounded to the hundredths place. If you use 3.14... the answer is 314.

Step 4: You've got your answer. Hope this helps!

Please answer this correctly and explain how you did it.

Pharmacy a lot!!!!
John arrived at work early in the morning at the home infusion pharmacy and discovered there was an order for furosemide 40 mg to be administered by IV infusion that needed to be sent out right away. He decided to mix the compound right away so it would be ready for the pharmacist to check when she arrived. He flipped a switch to turn the laminar flow workbench on and gather the needed materials. He put on a gown, washed his hands thoroughly, and place the supplies carefully in the hood. Because the furosemide was packaged in ampul, john remember to obtain a filter needle to remove any glass particle that might result from breaking the ampul. He attach the filter needle to the syringe and snap the tip of the ampul by holding it with his thumbs and index fingers and applying pressure with his thumbs. The glass scraped his finger as the lid came off, but there wasn’t much bleeding, so he continued. Using the filter needle and syringe, John withdrew the furosemide from the vile and carefully injected it into the injection ports of the piggyback bag. He remove the bag from the hood and placed it in the checking area, where he attached the appropriate labels. As he finished, the pharmacist arrived and came over to check the medication. John felt proud that he was able to complete the admixture in a timely manner so it could be sent out to the patient. The pharmacist checked the bank, initialed the paperwork, and sent back out for delivery.

Did john follow all the 797 guidelines for compounding a sterile product??
