Answer:

$\boxed {\boxed {\sf 254.34 \ yd^2}}$

Step-by-step explanation:

The area of a shape is the space occupied by the surface of an object. The area of a circle can be calculated using the following formula.

$a= \pi r^2$

The radius (r) of the center circle on the soccer field is 9 yards. We are asked to use 3.14 for pi.

r= 9 yd
π= 3.14

Substitute these values into the formula.

$a= (3.14)(9 \ yd)^2$

Solve the exponent.

(9 yd)² = 9 yd * 9 yd = 81 yd²

$a= (3.14)(81 \ yd^2)$

Multiply.

$a= 254.34 \ yd^2$

The area of the center circle on the soccer field is <u>254.34 square yards.</u>

Write any 4 laws of exponents.<br>

emmainna [20.7K]

$\rule{50}{1}\large\blue\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}$

<em>Write any 4 laws, or properties, of exponents.</em>

<em />

<em> </em> $\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}$

$\Large\text{Law number 1:-}$

$\Large\text{$a^n*a^m=a^{n+m}$}$

$\Large\text{It states that:-}$

When we multiply together numbers with the same base,

we add the exponents.

$\Large\text{Law number 2:-}$

$\Large\text{$a^m:a^n=a^{m-n}$}$

$\Large\text{It states that:-}$

When we divide numbers with the same base, we

subtract the exponents.

$\Large\text{Law number 3:-}$

$\Large\text{$(\displaystyle\frac{x}{y}) ^n=\frac{x^n}{y^n}$}$

$\Large\text{It states that:-}$

If we have a fraction to a power, we raise the numerator and

the denominator to that power.

And then last but not least,

$\Large\textit{Law number 4:-}$

$\Large\text{$a^{-m} =\displaystyle\frac{1}{a^m}$}$

$\Large\text{It states that:-}$

If we have a number with a negative exponent, we flip it over.

(-3,0);slope=2/3 slope intercept form

Step2247 [10]

Y = mx + b, m = slope and b = y-intercept

Because you don't have the y-intercept, you take the equation and replace x and y with the values given, then solve for b and replace b in the original equation with the value found.

y = 2/3x + b
0 = (2/3)(-3) + b
0 = -2 + b
2 = b

y = 2/3x + 2 is the answer
