What is the area of the sector with a central angle of 49° and a radius of 11 cm? Use 3.14 for pi and round your final answer to

olga_2 [115]

Answer:

$\boxed{\text{51.71 cm}^{2}}$

Step-by-step explanation:

If the angle θ is in radians, the formula for the area (A) of a sector of a circle is

A = ½r²θ

If θ is in degrees

$A = \dfrac{1}{2}r^{2}\theta \times \dfrac{\pi \text{ rad}}{180^{\circ}}= \pi r^{2}\times\dfrac{\theta }{360}$

Data:

θ = 49°

r = 11 cm

Calculation:

$\begin{array}{rcl}A& = &3.14\times 11^{2}\times\dfrac{49}{360}\\\\ & = &3.14 \times 121 \times 0.1361\\ & = & \mathbf{51.71}\\\end{array}\\\text{The area of the sector is }\boxed{\textbf{51.71 cm}^{2}}$

HW Set 1/ Directions: Solve each equ<br> 1. ) 4x + 27 = 3x

gavmur [86]

Answer:

x = -27

Step-by-step explanation:

4x+27=3x

Subtract 3x from both sides of the equation.

==> 4x + 27 -3x = 3x - 3x

==> 4x - 3x + 27 = 0

==> 1x + 27 = 0

Subtract 27 from both sides,

==> x + 27 - 27 = 0 - 27

==> x = -27
