Hei has the element shown for his science experiment. How many kilograms of the material does he have?
1 answer:
Answer:
3.508 kg of the material
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given that:
1 kilogram is 1000 grams.
A box that has three thousand, five hundred eight grams <=> 3508 grams
How many kilograms of the material does he have? we have got:
x kg - 3508g
<=> 1000x = 3508
<=>
<=> x = 3.508
So he has 3.508 kg of the material
Hope it will find you well.

First find the circumference of the circle.
Circumference:
Plug in 20 for the radius (r).
= 125.66
The circumference of the circle is 125.66 cm.
Now to find this in meters... there are 100 centimeters in 1 meter.
Divide 125.66 by 100 to find how many meters this is.
125.66 ÷ 100 = 1.26
The circle's circumference is 1.26 meters.
