Answer:

\huge\boxed{A_R=18\pi\ cm^2}

Step-by-step explanation:

\dfrac{80^o}{360^o}=\dfrac{8}{36}=\dfrac{2}{9}

The shaded region is 2/9 of whole circle.

Calculate the area of a circle:

A=\pi r^2

r - radius

Substitute r=9cm

A_O=\pi\cdot9^2=81\pi(cm^2)

Calculate the area of the shaded regions:

A_R=\dfrac{2}{9}A_O\\\\A_R=\dfrac{2}{9}\cdot81\pi=2\cdot9\pi=18\pi(cm^2)

You want to calculate the displacement of an object thrown over a bridge. Using -10 m/s^2 for acceleration due to gravity, what
MrRissso [65]

<u>Answer</u>

<em>The total displacement of the object is 320 m</em>

<u>Solution-</u>

From the formulas of mechanics,

s=ut+\frac{1}{2}at^{2}

Where,

s = displacement

u = initial velocity = 0               ( ∵ As the body was in rest in the beginning )

t = time taken = 8 s

a = acceleration = -10 m/s²      ( ∵ -ve is because of the downward motion)

Putting all the values,

s= 0 \times 8 + \frac{1}{2}(-10)8^{2} = -320 \ m ( ∵ -ve displacement means it is in downwards)

Solve for the missing variables, I know they add up to 360 but where do i start?
iren2701 [21]

Answer:

Step-by-step explanation:

a°=180°-36°=144° b°=180°-113°=67°

a°=144° and b°=67°

144+67=211

36+113=149

149+211=360
