Step-by-step explanation:
<h3>
Answer: 21.4 square meters</h3>
Work Shown:
A = area of the front triangular face
A = base*height/2
A = 2*1.7/2
A = 1.7
L = lateral area
L = (perimeter of the base)*(depth)
L = (2+2+2)*(3)
L = 18
SA = total surface area of a triangular prism
SA = 2*A+L
SA = 2*1.7+18
SA = 21.4 square meters
Answer:
4.2 cm
Step-by-step explanation:
Answer:
The length of the pendulum is 14.13 meters.
Step-by-step explanation:
The length of a pendulum is given by the formula,
, where T is the times period and L is the length of the pendulum.
Now, given that T = 2.4π seconds.
So, from the above equation, we get,

⇒ 
⇒
{We have the value of g as 9.81 m/sec²}
⇒ L = 1.44 × 9.81 = 14.13 meters. (Approx.)
Therefore, the length of the pendulum is 14.13 meters. (Answer)
