Question

what is the diameter of a solid right curcular cylinder whose height is 6cm and the area of the curved surface is 5 times of the combined area of two flat surfaces​

Answer 1

Answer:

the diameter is 2.4 cm

Step-by-step explanation:

h = 6 cm

area of 1 base is =π$r^2$

C.S.A = 5(2(π$r^2$))

2πrh = 10π$r^2$

2×6πr = 10π$r^2$

12πr = 10π$r^2$

$\frac{r^2}{r}$ = $\frac{12π}{10π}$

r = 1.2

diameter = 1.2*2 = 2.4

Answer 2

Answer:

2.4 is the answer of these questions
