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

Answers

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!

What is the radius, in centimeters, of a circle that has a circumference of 16π?

8
16
32
64

Answers

Answer: The radius equals 8cm

Answer:

8

Step-by-step explanation:

The circumference of a circle is equal to  π , which is a number  ≈ 3.14 , multiplied by the diameter of the circle.

Therefore,  C  =  π d .

We know that the circumference,  C , is  16 π , so we can say that:

16 π  =  π d

We can divide both sides by  π  to see that  16  =  d .

We now know that the diameter of the circle is  16 .

We also know that the diameter has twice the length of the radius.

In equation form:  2 r  =  d

2 r  =  16

r  =  8

Note that since  2 r  =  d , the equation  C  =  2 π r  holds and can be used in place of C  =  π d .
