Change it into improper fraction to make it easier or just solve it as is.
= $3\frac{5}{8}$ - $2\frac{7}{8}$
= $\frac{29}{8}$ - $\frac{23}{8}$
= $\frac{6}{8}$ = $\frac{3}{4}$
OR
= $3 \frac{5}{8}$ - $2 \frac{7}{8}$
divide it to two parts:
3-2=1 and $\frac{5}{8}$ - $\frac{7}{8}$ = $\frac{-2}{8}$
$1\frac{-2}{8}$ ⇒(1×8-2=6)
= $\frac{6}{8}$ = $\frac{3}{4}$

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:

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

Jeff drinks 2/3 of a glass of juice. write a fraction that is equivalent to 2/3

frutty [35]

Some fractions that are equivalent to 2/3 are 4/6 and 6/9
to find equivalent fractions, you just have to reduce the fraction or multiply both the top and bottom numbers by the same number to increase the fraction.
2/3 is as reduced as it can be, though.
