Question

Calcula el área lateral, total y el volumen

Answer 1

Hallamos g:

g² = R² + h²

g² = 4² + 7²

g² = 16 + 49

g²= 65

g = √65

g = 8.06 cm

Hallamos area lateral:

Al = (pi) × R × g

Al = 3.14 × 4 × 8.06

Al = 101.23 cm²

Hallamos area total:

At = (pi) × R × g + (pi) × R²

At = 101.23 + (3.14) × 4²

At = 101.23 + (3.14) × 16

At = 101.23 + 50.24

At = 151.47 cm²

Hallamos Volumen:

V = ((pi) × R² × h) / 3

V = (50.24 × 7)/3

V = 351.68/3

V = 117.227 cm³
