What is the area of the shaded sector

Whitepunk [10]

Answer:

Area = 634.21 square metre

Step-by-step explanation:

Area of shaded region = Area of the circle - Area of the sector

$Area \ of \ the \ circle = \pi r^2 = 225 \pi\\\\Area \ of \ the \ sector = \pi r^2 \frac{ \theta}{360} = \pi \times 225 \times \frac{37}{360}$

$Area \ of \ shaded \ region = 225 \pi - (225 \pi \times \frac{37}{360})$

$= 225 \pi (1 - \frac{37}{360})\\\\= 225 \pi \times 0.89722\\\\=634.21 m^2$

What is the value of x, when -9(x-5)=x+22 1/2

Kipish [7]

Answer:

x = 2.25

Step-by-step explanation:

-9(x - 5) = x + 22 1/2

Distribute the nine and then add 9x to both sides

-9x + 45 = x +22 1/2

+ 9x + 9x

Then try to get x alone

45 = 10x + 22 1/2

-22 1/2 -22 1/2

22.5 = 10x

$\frac{22.5}{10} = \frac{10x}{10}$

2.25 = x

F.8=8f? What is the answer

sveta [45]

Hey there!

f.8=8f

0.8f = 8f

SUBTRACT 8f to BOTH SIDES

0.8f - 8f = 8f - 8f

SIMPLIFY IT!

-7.2f = 0

DIVIDE -7.2 to BOTH SIDES

-7.2f/-7.2 = 0/-7.2

CANCEL out3 -7.2/-7.2 because it give you 1

KEEP: 0/-7.2 because it help solve for the f-value

NEW EQUATION: f = 0/-7.2

SIMPLIFY IT!

f = 0

Therefore, your answer is: f = 0

Good luck on your assignment and enjoy your day!
