A sculpture is made of solid nickel in the shape of a cone. The sculpture is 84 inches tall, and its base has a radius of 8 inches. If nickel costs $2.25 per cubic inch, how much did the nickel for the sculpture cost?
Use 3.14 for π, and do not round your answer.

Answers

Answer 1

Answer:

Cost = $12660.48

Step-by-step explanation:

Given that,

The height of the cone shape, h = 84 inches

The radius of base, b = 8 inches

The cost per cubic inch is $2.25.

The cost of nickel for the sculpture is given by :

[tex]C = 2.25\times \dfrac{1}{3}\pi r^2 h\\\\=0.75\times 3.14\times 8^2\times 84\\\\C=\$12660.48[/tex]

So, the required cost is equal to $12660.48.

The circumference of a circle is 8.44cm.
Find the length of the diameter.
Give your answer rounded to 2 DP.​

Answers

Answer:

Diameter = 2.68cm

Step-by-step explanation:

Circumference of a circle = 2πr

Circumference of a circle = 8.44cm

π = 3.14

r = ?

Circumference of a circle = 2πr

8.44 = 2 * 3.14 * r

8.44 = 6.28r

r = 8.44/6.28

r = 1.3439490445859

Approximately

r = 1.34

Diameter = 2r

Diameter = 2 * 1.34

Diameter = 2.68cm

Approximately 0.45 m. A mountain bike tire has a diameter of approximately. 0.6 m. In a 400-m race, how many more times will the BMX bike tire have to turn than the mountain bike tire?

Answers

Answer:

71 times

Step-by-step explanation:

Diameter of BMX bike= 0.45m

Radius= 0.225m

Cirumference of BMX bike

C= 2πr

C=2*3.142*0.225

C= 1.4139m

In a 400-m race, the BMX bike will turn

=400/1.4139

=282.9 times

=283 times

Diameter of  Mountain bike= 0.6m

Radius= 0.3m

Circumference of Mountain bike

C= 2πr

C=2*3.142*0.3

C=1.8852m

In a 400-m race, the Mountain bike will turn

=400/1.8852

=212.17 times

=212 times

Hence the difference is

=283 -212

=71 times

What is the domain for the relation R={(2,3),(1,3),(-2,1),(1,1)}?

Answers

Answer:

Step-by-step explanation:

There are four points here.  We look at the x-values and identify {2, 1, -2, 1].  This can be reduced to {-2, 1, 2}

Unfortunately, the input '1' shows up twice and thus the relation cannot be a function; we cannot have two different y-values for the same x-value (1).

The ratio of the number of Baskin Robbins :Cold stone ice cream cones sold in a day is 11:9.If the number of Baskin Robbins cone sold is 44 .(a)How many cold stone cones are sold ? (b)If the number of cold stone cones on the next day is reduced to 20.what is the new ratio?

answer fast plsssssssssssssssssssssssssssssssss

Answers

Answer:

a) 36

b) 11:5

Step-by-step explanation;

a) let the number of cold stone cones be x

Since the initial ratio is 11:9

we have the ratio of the ice creams as;

11:9 = 44:x

11/9 = 44/x

11 * x = 9 * 44

x = (9 * 44)/11

x = 9 * 4 = 36

b) Now, from 36, we have a number of cold stones as 20

So the ratio now will be;

44:20

and that would be;

11:5
