A sector with a radius of 6 cm has a central angle measure of 4pi/9 in radians. What is the area of the sector?
Angelina_Jolie [31]

Answer:

8πcm² = 8pi cm²

Step-by-step explanation:

The formula for area of a sector = ½r²θ

Where r = radius = 6cm

θ = central angle = 4pi/9 in radians = 4π/9

Area of the sector = 1/2 × 6² × 4π/9

Area of the sector = (144π/18)cm²

Area of the sector = 8πcm²

Therefore, Area of the sector =

8πcm² = 8pi cm²

Simplify. 192−−−√ 83√ 643√ 106√ 824−−√
makvit [3.9K]

Answer:

192 - 4√291341371

Step-by-step explanation:

If your question is: 192 - √83(√643)(√106)(√824) - √0

Then you multiply all the √s together and then subtract it from 192. √0 is 0, so you don't have to worry about that.

If your question is to <em>simplify</em> 192 in √ form, then the answer is none of the above. To find the √ form of 192, square it: 192² = 36864. So to simplify 192 in √ form, it would be √36864.

The perfect square:

(a+b)^2=a^2+2ab+b^2

Q4

We have

y^2+14y+49=0\\\\y^2+2(y)(7)+7^2=0\\\\(y+7)^2=0\iff y+7=0\qquad\text{subtract 7 from both sides}\\\\\boxed{y=-7}

Q5

We have

y^2+16y+64=0\\\\y^2+2(y)(8)+8^2=0\\\\(y+8)^2=0\iff y+8=0\qquad\text{subtract 8 from both sides}\\\\\boxed{y=-8}
