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 1

Answer:

314 ft squared

Step-by-step explanation:

A = πr^2 = π · 102 ≈ 314.15927

Answer 2

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!

Answers

Answer:

the probability of selecting a number less than 10 is 4/9, or 0.44.

Step-by-step explanation:

There are 4 numbers less than 10, out of a total of 9 numbers.

Thus, the probability of selecting a number less than 10 is 4/9, or 0.44.

4/9 is the answer because there is 9 numbers and 4 of them are less then 10.

Step-by-step explanation:

Based on this exercise, the true inequalities are:

0 < √8 ≡ 0 < 2.8284.√8 < 3 ≡ 2.8284 < 3.√8 > √7 ≡ 2.8284 > 2.6458.1 < √8 ≡ 1 < 2.8284.

What is an inequality?

An inequality is a mathematical relation that can be used to compare two (2) or more integers in an equation based on any of the following:

Less than (<).Greater than (>).Less than or equal to (≤).Greater than or equal to (≥).

In order to determine the true inequalities, we would evaluate each of the inequalities as follows:

0 < √8 ≡ 0 < 2.8284 (True).√8 < 3 ≡ 2.8284 < 3 (True).√8 > √7 ≡ 2.8284 > 2.6458 (True).√8 < 2 ≠ 2.8284 > 2 (False).√8 > 8 ≠ 2.8284 > 8 (False).1 < √8 ≡ 1 < 2.8284 (True).
