6 0

Answer:

556 ft²

Step-by-step explanation:

The given information is,

→ Length (l) = 11 ft

→ Breadth (b) = 10 ft

→ Height (h) = 8 ft

Formula we use,

→ 2(lb + bh + lh)

The surface area of cuboid will be,

→ 2(lb + bh + lh)

→ 2{(11 × 10) + (10 × 8) + (11 × 8)}

→ 2(110 + 80 + 88)

→ 2 × 278

→ [ 556 ft² ]

Therefore, the TSA is 556 ft².

What is the angular velocity of a point that rotates through
ivann1987 [24]

Answer:

Option A

Step-by-step explanation:

Angular velocity of an object is defined by,

Angular velocity (w) = \frac{\triangle \theta}{\triangle t}

Here, Δθ = Change in angle of rotation

Δt = Duration or time

In this question Δθ = \frac{7\pi }{2} radians and Δt = 24 seconds

Therefore, angular velocity = \frac{\frac{7\pi }{2} }{24}

                                              = \frac{7\pi }{48} radians per second

Option A is the answer.
