saveliy_v [14]

Answer:

(-2,0)

Step-by-step explanation:

remember the rule for 90 degree clockwise is (-y,x) opposite y and x

the negative in there DOES NOT mean it will always be negative it means opposite but in this case yes it's negative because the opposite of positive is negative

Here we go ~

  • take value of pi = 3

  • r = radius = 5 cm

  • h = height = 9 cm

Let's calculate volume of Cylinder ~

\qquad \sf  \dashrightarrow \:v =  \pi {r}^{2} h

\qquad \sf  \dashrightarrow \:v = 3 \times  {5}^{2}  \times 9

\qquad \sf  \dashrightarrow \:v =  3\times25 \times 9

\qquad \sf  \dashrightarrow \:v = 75 \times 9

\qquad \sf  \dashrightarrow \:v =67 5 \:  \: cm {}^{3}

That's all, ask me if you have any queries ~

A helicopter flew north 325 meters and then flew east 500 meters. How far is the helicopter from its starting point?
kati45 [8]

Answer:

596.34m approx

Step-by-step explanation:

Given data

Let the Starting point be x

A helicopter flew north 325 meters from x

Then flew east 500 meters

Let us apply the Pythagoras theorem to solve for the resultant which is the distance from the starting position

x^2= 325^2+500^2

x^2=105625+250000

x^2= 355625

x= √355625

x=596.34m

Hence the distance from the starting point is 596.34m approx
