Answer:
35 Cubic Centimeters
Step-by-step explanation:
Answer:
The answer is 0.006667
Step-by-step explanation:
The answer is 0.06667 because .02 divided by 3 equals 0.006667.
if its diameter is 4 inches, then its radius is half that, or 2 inches.
Answer:
A(r) = √2 * r
A(r) Domain is R { r ; r > 0}
Step-by-step explanation:
Diagonals of a square intercept each other in a 90° angle. The four triangles resulting from diagonal interception are equal and are isosceles triangles, with hipotenuse a side of the square
Therefore we apply Pythagoras theorem
Let x be side of square, and r radius of the circle, ( diagonals touch the circle) then
x² = r² + r²
x² = 2r²
x = √2 * r
Now Aea of square is :
A = L² where L is square side
A(r) = √2 * r
Domain of A(r) = R { r, r > 0}
the volume of the sphere is =4/3.pi.r^3
