Answer: (3,-2)

Step-by-step explanation:

$-3x-7y=5\\15x+6y=33$

$5(-3x-7y)=5(5)\\-15x-35y=25$

new system:

$-15x-35y=25\\15x+6y=33$

add.

$-29y=58\\y=-2$

plug in -2 for y

$-3x-7(-2)=5\\-3x+14=5\\-3x=-9\\x=3$

system:

$(3,-2)$

A circle with radius 6 has a sector with a central angle of 48 what is the area of the sector

inn [45]

Answer:

≈ 15.08 units²

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{48}{360}$ ( r is the radius )

= π × 6² × $\frac{48}{360}$

= 36π × $\frac{48}{360}$ = π × $\frac{48}{10}$ = $\frac{48\pi }{10}$ ≈ 15.08

Find the area of the circle r=14m use pi=3.14 and round your answer to the nearest hundredth

pantera1 [17]

Answer:

<h2>The answer is 615 m²</h2>

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius

From the question

r = 14 m

π = 3.14

The area of the circle is

A = 3.14 × ( 14 ) ²

= 3.14 × 196

= 615.44

We have the final answer as

<h3>615 m² to the nearest whole number</h3>

Hope this helps you
