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:

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

Whats 12*5+55= <br><br> ill mark asa brainliest

Aleksandr-060686 [28]

First do PEMDAS
There's no parenthesis. So move on to exponent. There's also no exponents. Move on to multiplication. There it is.

12×5=60.

There's no division so now next one is addition. Hey look! There is addition.

60+55=115.

So 115 is your answer.

Answer:

Step-by-step explanation:

On the first side it shows 5 ones. If you add 5 by 2 it’s 7. Then on the other side it shows 3 X’s. 3x2 is 6. Plus you add that 1 which makes it 7.

Hope this Helps :)
