We find the volume of the ball in cubic inches:
V = 4/3 πr³
V = 4/3 x π x 5³
V = 523.6 cubic inches
Weight = 1/100 x 523.6
Weight = 5.24 pounds.
Answer:
Not enough information.
Step-by-step explanation:
AB + BC + CD + DA = 46
In a parallelogram, opposite sides are congruent.
AB + DA + AB + DA = 46
2AB + 2DA = 46
We have two unknowns and only one equation.

€1 = $1.10
€90 = $99
$99 - $63 = $36
$36 / $1.20 = $30
$36 = €30
Answer €30
Answer:
The area of the circle is 314mm²
Step-by-step explanation:
To solve this problem we have to use the formula for calculating the area of a circle
a = area
π = 3.14
r = radius
d = diameter
r = d/2
r = 20mm / 2
r = 10mm
a = π * r²
we replace the known values
a = 3.14 * (10mm)²
a = 3.14 * 100mm²
a = 314mm²
The area of the circle is 314mm²
