Question

Porfavor me pueden ayudar con la pregunta 2 y la pregunta 3 porfavor

Answer 1

Explicación paso a paso:

2.

volúmen de un cilindro = A x h

Abase = π r^2

Abase = π (7/2)^2

Abase = π (3.5)^2

Abase = π ( 12.25 )

Abase = 38.48 cm^2

Vol. = Abase x h

vol. = 38.48 x 13

Vol. = 500.30 cm^3

------------------------------------

3.

Acirculo = π r^2

Acirculo = π (15/2)^2

Acirculo = π (7.5)^2

Acirculo = π (56.25)

Acirculo = 176.71 m^2
