Answer:
we divide 192 by the volume 19.5
192÷19.5=9.85 so the necklace is made of bronze
Answer:
radius = 5 in
Step-by-step explanation:
Using the formula for calculating the area (A) of a circle
A = πr² ( r is the radius )
here A = 78.5, hence
3.14r² = 78.5 ( divide both sides by 3.14 )
r² =
= 25 ( take the square root of both sides )
r =
= 5
Answer:
To calculate the radius of a circle by using the circumference, take the circumference of the circle and divide it by 2 times π.
Yes. but if it has a negative sign in the front of it it is below sea level.
(2+5x)-2=18
2+5x-2=18
5x=18
x=18/5= 3.6
