Answer:
r = 1.0 cm to the nearest tenth
Step-by-step explanation:
The formula for the area of a circle of radius r is A = (pi)r². So, from the given information we need to determine the radius of the orange. The volume formula is V = (4/3)(pi)r³ and in this case V = 113.1cm³. Thuis,
(4/3)(pi)r³ = 113.1cm³
3 3(113.1 cm³)
Multiplying both sides by ------------ , we get r³ = --------------------- , and so
4(pi) 12.57
r³ = 339.3 cm³ / 12.57 ≈ 0.997, so that r ≈ ∛(0.997 cm³) ≈ 0.9999, or
r = 1.0 cm to the nearest tenth.
