Respuesta:
V = 9π/2
Explicación paso a paso:
Datos:
hipotenusa = generatriz = √10cm
a = base = x
b = altura = 3x
teorema de Pitágoras
h² = a² + b²
(√10cm)² = x² + (3x)²
10 cm² = x² + 9x²
10 cm² = 10x²
x² = 10/10
x² = 1
√x² = √1
x = 1
a = base = x = 1 ( radio )
b = altura = 3x = 3(1) = 3
V = π x r² x b / 2
V = π x 1² x 3² / 2
V = π x 1 x 9 /2
