Answer:
D
Step-by-step explanation:
1, 17, and 20 are very different from the average numbers in this list.
area of shaded region = 1/4 of the circle area - triangle area
circle area = pi x r² = 3,14 x 2² = 12,56 m²
so 1/4 circle area = 12,56 : 4 = 3,14 cm²
and
triangle area = 1/2 x 2 x 2 = 2 m²
=> area of shaded region = 1,14 cm²
Answer:
153 s
Step-by-step explanation:
Given:
The variation of height of a rocket above ground with time 't' is given as:
In order to reach the ground, the height will be 0 feet.
So, plugging in 0 for 'h' and solving for time 't', we get:
So, at time , the rocket is at the ground or it is its launch point. Then after 153 seconds, it will again reach the ground.
So, the time it take for the rocket to hit the ground is 153 s.
