Question

13.- Calcular la altura de un cilindro cuya masa es de 120 gramos y tiene 4,7 g/cm3 de densidad? El radio del cilindro es igual a 4 cm.​

Answer 1

Answer:

As per given Question

$\bf \rm \: A = \dfrac{1}{2}h(b_1 + b_2)$

we have been asked to solve this equation for h .

$\implies \rm \: A = \dfrac{1}{2}h(b_1 + b_2) \\ \\ \implies\rm \: 2 A = 1(b_1 + b_2) \\ \\ \implies\rm \: 2 A = h(b_1 + b_2) \\ \\ \implies \rm \: \dfrac{2A}{(b_1 + b_2)} = h \\ \\ \implies \rm \: h = \: \dfrac{2A}{(b_1 + b_2)}$

So, the required option is c .
