Find

Sedaia [141]

Answer:

The amount of steel used = 94.38 $m^{2}$

Step-by-step explanation:

Height of the tank = 4.5 m.

Diameter of the tank = 4.2 m.

But,

radius = $\frac{diameter}{2}$

= $\frac{4.2}{2}$

radius = 2.1 m

Total surface area of a cylinder = 2 $\pi$ rh + 2 $\pi$ $r^{2}$

= 2 $\pi$ r(r + h)

= 2 x $\frac{22}{7}$ x 2.1 (2.1 + 4.5)

= 44 x 0.3 (6.6)

= 87.12

Total surface area of a cylinder = 87.12 $m^{2}$

Since $\frac{1}{12}$ of the steel was wasted, then;

$\frac{1}{12}$ x 87.12 = 7.26 $m^{2}$

Actual area of steel sheet used = 87.12 + 7.26

= 94.38 $m^{2}$

Thus, 94.38 $m^{2}$ of steel was used in making the tank.

2. Evaluate the expression for q = 2 6

GenaCL600 [577]

Answer:

Step-by-step explanation:

This may not be intirely correct because you said q = 2 6. I think that means 2 times 6.

Anyways

2 x 6 = 12

⇒ q = 12
