Answer 1

Respuesta:

P = perimetro = suma de todos los lados

Ab = Area de la base

h = Altura

b)

Ap = Apotema = 6.9cm

P = 5*10cm = 50cm

Ab = (Ap*P)/2 = (6.9m*50cm)/2 = 172.5cm²

V= (Ab*h)/3 =(172.5cm²*5cm)/3 = 287.5cm³

a)

P = 5*4.2cm = 21cm

Ab = (Ap*P)/2 = (3.5cm*21cm)/2 = 36.75cm²

V = Ab*h = 36.75cm²*5cm = 183.75cm³

c)

Vt= volumen total

Vco= volumen cono

Vci= columen cilindro

Vt = Vci+Vco

Vco = (π*r²*h)/3 = ( (3u)²*4u*π )/3 = (12π)unidades³ ≅ 37.69u³

Vci = (π*r²*h) = ( (3u)²*10u*π ) = (90π)unidades³ ≅ 282.74u³

Vt = 12πu³ + 90πu³ = 102πu³ ≅ 282.74u³ + 37.69u³ ≅ 320.43u³
