Just count the grids
He will need 17 inches of ribbon.
The diagonal splits the square into two right triangles. We can then use the Pythagorean theorem to find the length of the diagonal (the hypotenuse of the triangle):
12² + 12² = x²
144 + 144 = x²
288 = x²
Take the square root of both sides:
√288 = √x²
16.97 = x
17≈x
Answer:
Diameter = 8 cm
Radius = 8/2 = 4 cm
Height = 12 cm
Volume of cone = 1/3πr^2h = 1/3 (4)^2 × 12π
= 64π cubic cm
Radius of lead = 4mm = 0.4 cm
Volume = 4/3πr^3 = 4/3 × (0.4)^3π = 0.256/3π cubic cm
Total number of balls = 64π÷ 0.256/3π = 750
