Question

Please help me find the volume of this figure

Answer 1

3571.25 volume of figure

Answer 2

Answer:

V = 3964.048623cm³

Step-by-step explanation:

Part 1: Find the volume of the cube

The formula of the volume of a cube: V = a³

Given that: a = 15cm

Substitute: V = (15cm)³ = 3375cm³

Part 2: Find the volume of the cylinder

The formula of the volume of a cylinder: V = πr²h

Given that: d = 5cm, r = 2.5cm, and h = 30cm

Substitute: V = π(2.5cm)²(30cm) = 589.0486225cm³

Part 3: Sum of all volumes

V = 3375cm^3 + 589.0486225 cm³

V = 3964.048623cm³

If you are being instructed to give the answer in the right number of significant figures, which in this case, is 1 SF, the answer is:

V ≈ 4 x 10³ cm³
