Find the circumference of a circle that has a diameter of 5. Use 22/7 for pi

Mathematics
1 answer:
anastassius [24]3 years ago
3 0
The circumference of a circle is 2 \pi r since the radius is half of the diameter we can substitute the diameter instead of using 2r. So we get \pi d The we can substitute the given diameter, which is 5 and multiply it by \frac{22}{7} and get \frac{110}{7}.

What’s the correct answer for this question?
Korvikt [17]

Answer:

1)

Volume of pyramid = 1/3(Ab)(h)

Where Ab is the area of base, h is height

Volume of cone = 1/3(Ab)(h)

a) Their formula for finding volume is same. Also, their painting heads are same.

b) Pyramids have a tetragonal base while cones have a polygonal base

2) Pyramids

Volume of cone = (1/3) πr²h

Since Area of a circle = πr²

So

Volume of pyramid = (1/3)(A)(h)

So we can use the formula of a circle in cone's formula

Complete the equation of the line through (-9,-9) and (-6,0)
Rudik [331]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis.

According to the data of the statement we have the following points:

(x_ {1}, y_ {1}): (- 9, -9)\\(x_ {2}, y_ {2}): (- 6,0)

We found the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {0 - (- 9)} {- 6 - (- 9)} = \frac { 9} {- 6 + 9} = \frac {9} {3} = 3

Thus, the equation is of the form:

y = 3x + b

We substitute one of the points and find b:

0 = 3 (-6) + b\\0 = -18 + b\\b = 18

Finally, the equation is:

y = 3x + 18

Answer:

y = 3x + 18

What’s the sum of interior angles of a 45-gon?
Mashutka [201]

Answer:

Step-by-step explanation:

As each exterior angle is 45o , number of angles or sides of the polygon is 360o45o=8 . Further as each exterior angle is 45o , each interior angle is 180o−45o=135o .

sal makes a 10% commission on the first $5000 of sales and 15% on any sales over $5000. find his total graduated commission on $
Helga [31]
0.10(5000) = 500
0.15(10,000) = 1500

total commission on 15,000 = (150 + 500) = 2,000
