Question

Please someone help me ITS URGENT I WILL BRAINLIST UUUU AND MARK U 5 star!! ANYONE WHO IS GOOD AT MATHS?..

Answer 1

Answer:

diameter=30cm

radius=30/2=15

volume of cylinder = pi×r²×h

volume of cylinder=3.14×15²×40cm

volume of cylinder=28,260cm³

Answer 2

Answer:

28260 cubic cm

Step-by-step explanation:

Given,

Diameter of the cylinder = 30cm

So, radius of the cylinder = 30cm ÷2 = 15 cm

Height of the cylinder = 40 cm

There, volume of the cylinder,

$= \pi {r}^{2} h$

$= 3.14 \times 15cm \times 15cm \times 40cm$

$= {28260cm}^{3}$
