Answer:

See below.

Step-by-step explanation:

1) Please check the number of volume of steel. It should be 54,259.2

{cm}^{3}

. Not 54,259.2 cm. Right?

2) If so,

First

The volume of single rod

=  \pi \times ( { \frac{4}{2} })^{2} \times 60= \pi \times  {2}^{2} \times 60= 4\pi \times 60= 4 \times 3.14 \times 60= 753.6 {cm}^{3}

The number of rods

=  \frac{54259.2}{753.6}  = 72

In a GP the second and fourth terms are 0.04 and I respectively find the common ratio and the first term​
Reptile [31]

Answer:

common ratio=0.5, a1= 0.08

Step-by-step explanation:

r=a3/a2

r=a4/a3

compare both we get:

a3/a2=a4/a3

subtitute a2=0.04 and a4=1

a3/0.04=1/a3

(a3)^2=0.04*1

(a3)^2=0.04

taking square root in both sides

a3=0.02

For r, r=a3/a2

subtitute a3 and a2 above

r=0.02/0.04

r=0.5 common ratio

For a1

r=a2/a1

0.5=0.04/a1

a1=0.04/0.5

a1=0.08
