The density of copper is 9.86g\cm³ work out the solid copper cuboid in kg

Mathematics
1 answer:
EleoNora [17]3 years ago
3 0

Answer:

Step-by-step explanation:

Density of copper = 9.86 g / cm^3 = 9860 kg / m^3

= 9.86 x 1 / 1000 kg / cm^3 = 9.86 / 1000 Kg / cm^3

= 0.00986 kg / cm^3

= 9.86 x 1 / 1000 kg (1 / 100 m)^3

= 9.86 x 1000000 / 1000 kg / cm^3

Mass "m" = 9860 kg / m^3

thus the mass of copper in solid form is m =  9860 kg / m^3

Answer:

4 cups of sugar require 14 cups of sugar

Step-by-step explanation:

Given

\frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar

Required

Determine the cups of flour for 4 cups of sugar

First, we need to determine the unit rate for 1 cup of sugar.

This is done by multiplying both sides by 4

4 * \frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar * 4

\frac{7}{2}\ cup\ flour = 1\ cup\ sugar

Next, we determine cup of flour for 4 cups of sugar.

This is done by multiplying both sides by 4

4 * \frac{7}{2}\ cup\ flour = 1\ cup\ sugar * 4

2 * 7\ cup\ flour = 4\ cup\ sugar

14\ cup\ flour = 4\ cup\ sugar

<em>Hence;4 cups of sugar require 14 cups of sugar</em>

I need help with this .
vaieri [72.5K]
I would be glad to help you! I will solve through 3 to get you started.

This is a very important concept, so it would be helpful if you learn it on your own.

C= 2* pi* r

1. The radius is 5 cm. 5 cm represents r in the equation.
C= 2* 3.14 (or pi)* 5 
Multiply it by using a calculator. 
My answer was 31.4.

Let's try the second one.
2. The diameter is 9. Have of the diameter is the radius. 
9/2= 4.5 
Plug it into the equation.
C= 2*3.14*4.5
I got 28.26

One more. 
Plug it into the equation.
C= 2*3.14*5.6
35.17 was my answer.

Make sure to add the end signs to you answer, ft, cm, meter, etc.

Let me know if you need more help.

Brainliest answer is always appreciated.

It would be 224 , the base is 64 and every triangle is 80 but if you follow the rule for area to a triangle you get 40
So 64+40+40+40+40= 224
