A circle has a central angle measuring StartFraction 7 pi Over 10 EndFraction radians that intersects an arc of length 33 cm. Wh

NeTakaya

Answer:

15 cm.

Step-by-step explanation:

It is given that,

Central angle $=\dfrac{7\pi}{10}$

Arc length = 33 cm

Formula for arc length :

$s=r\theta$

where, s is arc length, r is radius and $\theta$ is central angle in radian.

Substitute s=33 and $\theta=\dfrac{7\pi}{10}$ in the above formula.

$33=r\left(\dfrac{7\pi}{10}\right)$

Multiply both sides by 10.

$330=7\pi r$

Divide both sides by $7\pi$ .

$\dfrac{330}{7\pi}= r$

Put $\pi=3.14$

$\dfrac{330}{7(3.14)}= r$

$15.0136= r$

$r\approx 15$

Therefore, the radius of the circle is 15 cm.

-2x+3y=-13 and 3x-3y=12

Tresset [83]

Answer:

x = -1 ,y = -5

Step-by-step explanation:

--> -2x + 3y +3x-3y = 12-13

--> x= -1

then

--> -2(-1) +3y =-13

--> 2+3y= -13

--> 3y = -15

--> y =-15/3

--> y = -5
