If pie-0 =3.14159265359 what is pie time 160=
Zepler [3.9K]

Answer:

Hey!

To start this problem, we'll most likely need a calculator. Handling \pi can get a little messy, and tricky.

(also note that "pie" is a food, the mathematical term \pi, is pronounced "pie", but spelled "pi.")

Anyway, multiplying 3.14159265359..... (\pi) \cdot 160 = 502.654824574...... going on and on.

In general, these types of problems are better for a calculator if you want an exact answer. Otherwise, just resort to estimation. \pi is pretty close to 3.14.

160 \cdot 3.14 = 502.4, which is decently close to our other answer.

Hope this helps!

Find the Perimeter and Area
igor_vitrenko [27]

Answer:

Area = 20.28 cm^2

Perimeter = 16.28 cm

Step-by-step explanation:

The figure is composed of a half circle and a rectangle,

The circle has a diameter of 7 - 2 - 1 = 4cm and the rectangle is of side 2 cm and 7 cm.

Therefore the area is :

Area = A rectangle + Acircle/2 = 2*7 + pi*r^2/2 = 20.28 cm^2

The perimeter is :

Perimiter = 1 + 2 + 7 + Pcircle/2 = 1 + 2 + 7 + 2*pi*r/2 = 16.28 cm

Find the equation of the line parallel to y=x-3 that also intersects the points (3,-2)
Reika [66]

Answer:

y = x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x - 3 ← is in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes, hence

y = x + c ← is the partial equation of the parallel line.

To find c substitute (3, - 2) into the partial equation

- 2 = 3 + c ⇒ c = - 2 - 3 = - 5

y = x - 5 ← equation of parallel line
