2. It is required to make a closed cylindrical tank of height 1 m and base diameter 140 cm

4vir4ik [10]

Answer:

It's required $7.48\ m^2$ of sheet for the tank

Step-by-step explanation:

<u>Surface Area of a Cylinder</u>

Given a right cylinder of base radius r and height h, the surface area is calculated as follows:

$S=2\pi r^2+2\pi r h$

The cylindrical tank has a height of h=1 m and a base diameter of 140 cm. The radius is half the diameter, thus r=140/2 = 70 cm = 0.7 m. Substituting:

$S=2\pi 0.7^2+2\pi (0.7)(1)$

$S=2\pi 0.49+1.4\pi$

$S=2.38\pi$

$\boxed{S=7.48\ m^2}$

It's required $7.48\ m^2$ of sheet for the tank

Answer:

1800

Step-by-step explanation:

Labor quantity variance= Actual quantity ×standard price - standard quantity ×standard price

Standard quantity=2×2600=5200

Labor quantity variance

5050×12-5200×12=1800
