Find the area of a circle

Mathematics

Answer:

28.26 square feet

Step-by-step explanation:

Area of a circle is: A=\pi r^2

'r' is the radius.

We are given the diameter of 6ft. Since the diameter is twice the radius, the radius is 3 ft.

6/2 = 3

Using 3.14 for pi:

A=3.14*3^2\\\rightarrow 3^2=9\\A=3.14*9\\\boxed{A=28.26}

The area of the circle should be 28.26 square feet.

Answer:

28.26 ft²

Step-by-step explanation:

If the diameter is 6 feet, then the radius is 3 feet since 2r=d

The area formula in this case is 3.14×r² since it says "Use 3.14 for π".

3.14×3²=

3.14×9=

28.26 ft²

HELP ASAP ITS SO HARD! Kelsey did the following division problem. Her teacher says that the quotient she found is wrong. −2 5/6
SpyIntel [72]

Part A

Her steps were

-2 \frac{5}{6} \div 1 \frac{1}{3}\\\\-\frac{17}{6} \div \frac{4}{3}\\\\-\frac{6}{17} \times \frac{3}{4}\\\\-\frac{6\times 3}{17\times4}\\\\-\frac{18}{68}\\\\-\frac{9}{34}\\\\

Kelsey made a mistake on line 3. Note how the 17/6 flips to 6/17. This is not correct. You keep the first fraction the same, but you do flip the second fraction. This only applies when you divide two fractions.

The third step should look like -\frac{17}{6}\times \frac{3}{4}

=======================================================

Part B

Here's what she should have written

-2 \frac{5}{6} \div 1 \frac{1}{3}\\\\-\frac{17}{6} \div \frac{4}{3}\\\\-\frac{17}{6} \times \frac{3}{4}\\\\-\frac{17\times 3}{6\times 4}\\\\-\frac{51}{24}\\\\-\frac{17}{8}\\\\

If you want to convert that improper fraction to a mixed number, then you could do something like this

-\frac{17}{8} = -\frac{16+1}{8}\\\\-\frac{17}{8} = -\frac{16}{8}-\frac{1}{8}\\\\-\frac{17}{8} = -2 \frac{1}{8}\\\\

Or you could divide 17 over 8 using long division to get 2 remainder 1. The 2 is the quotient that goes to the left of the 1/8. The remainder of 1 is the numerator of 1/8.
