777dan777 [17]

Answer:

B. 53.1 cm³

Explanation:

$\sf volume \ of \ cone: \dfrac{1}{3} \pi r^2h \ \ \ \ (r \ is \ radius, \ h \ is \ height)$

Here Given:

height: 11.5 cm

diameter: 4.2 cm

radius: d/2 = 4.2/2 = 2.1

Volume:

$\sf \cdot \ \dfrac{1}{3} \pi r^2h$

$\sf \cdot \ \dfrac{1}{3} (3.14) (2.1)^2(11.5)$

$\sf \cdot \ 53.11 \ cm^3$ ≈ $\sf 53.1 \ (rounded \ to \ nearest \ tenth)$
