Answer 1

Required Answer:-

$\large{ \underline{ \boxed{ \purple{ \bf{Statement - 1}}}}}$

Given that the length of the hall is 36 m and the breadth is 24 m long. Let h be the height of the hall.

Now:

We know the formula for finding the Lateral surface area of a cuboid i.e. 2h(l + b) unit².

Area to be papered = 2h(l + b) - 40 m²

Total cost = Total area × Cost

Plugging the values:

⇒ {2h(l + b) - 40} × Rs. 8.40 = Rs. 4704

⇒ 2h(36 + 24) - 40 = 560

⇒ 2h(60) = 560 + 40

⇒ 120h = 600

⇒ h = 5 m

$\therefore$ Statement 1 is absolutely correct✓

$\large{ \underline{ \boxed{ \purple{ \bf{Statement - 2}}}}}$

Let the radius of the circle be r.

Then circumference will be 2πr and diameter of the circle will be 2r. Their difference is 154 cm.

The equation will be like:

⇒ 2πr - 2r = 154 cm

⇒ 2r(π - 1) = 154 cm

⇒ 2r(15/7) = 154 cm

⇒ r × 30/7 = 154 cm

⇒ r = 154 × 7/30 cm

⇒ r = 35.93 cm (approx.)

$\therefore$ Statement 2 is incorrect.

━━━━━━━━━━━━━━━━━━━━

Statement 1 is true and Statement 2 is false. This is the correct alternative (Option C).
