Find the area of the sector

sergij07 [2.7K]

Answer:

$\boxed {\boxed {\sf a \approx 190.9 \ yd^2}}$

Step-by-step explanation:

There are 2 formulas for the area of a sector, but since we are given the central angle in degrees (not radians), we will use this formula:

$a= \frac {\theta}{360} \times \pi r^2$

Where θ is the central angle and r is the radius.

For this circle, the radius is 9 yards and the central angle is 270 degrees. We can substitute these values into the formula.

$a= \frac {270}{360} \times \pi \times (9 \ yd )^2$

Solve the fraction.

$a=0.75 \times \pi \times (9 \ yd)^2$

Solve the exponent.

(9 yd)²= 9 yd* 9 yd=81 yd²

$a= 0.75 \times \pi \times 81 \ yd^2$

Multiply all three numbers together.

$a= 190.851753706 \ yd^2$

The question asks us to round to the nearest tenth.

190.8<u>5</u>1753706

The 5 in the hundredth place tells us to round the 8 up to a 9.

$a \approx 190.9 \ yd^2$

The area of the sector is approximately <u>190.9 square yards. </u>

I need help with Function Operations please

Alex787 [66]

Answer:

Step-by-step explanation:

The ring operator signifies a composition of functions. The composition is evaluated right-to-left. That means the composition ...

$(f\circ g)(x)$

should be interpreted to mean ...

$f(g(x))$

___

To evaluate f(g(6)), we first evaluate g(6):

g(6) = 6² -5 = 31

Then we evaluate the function f using that as its argument:

f(31) = 31 -1 = 30

f(g(x)) = 30
