Question

URGENTEEEEE PLS!!!!!!!​

Answer 1

Respuesta:

17231,49 cm²

23,417

Explicación paso a paso:

3)

Área = 2 (π(32 cm)²) + (64π cm)(h)

tg(40°) = h/64 cm

h = tg(40°) * 64 cm

h = 53,702 cm

Área = 2048π cm² + 3436π cm²

Área = 17231,49 cm²

4)

tg(63,44°) = √20/r

r = √20/ tg (63,44)

r = 2,236067

Volumen cilindro:

V = π(2,236067)² * √20

V = 5π * √20

V = 70,2481

Volumen esfera:

V = 4/3 * π (2,236067)³

V = 43,832

Volumen de agua

V = 70,2481 - 43,832

V = 23,416
