Question

A cylinder has height of 10 millimeters and radius 12 millimeters.Find the a.volume and b. surface area.

Answer 1

Answer:

A. Volume = 4,523.9 mm³ (cubic mm)

B. Surface area = 1,658.76 mm² (square mm)

Step-by-step explanation:

A. Lest's calculate the volume of the cylinder:

r = 12 mm, h = 10 mm

Volume = π * r² * h

Volume = 3.1416 * 12² * 10

Volume = 3.1416 * 144 * 10

Volume = 4,523.9 mm³

B. Let's calculate the surface area of the cylinder:

Surface area = 2π * r * h +2π * r²

Surface area =2π * 12 * 10 + 2π * 12²

Surface area = 6.2832 * 120 + 6.2832 * 144

Surface area = 753.98 + 904.78 = 1,658.76 mm²
