Answer:

The area of the circle is 9 \pi\ units^{2}  or  28.26\ units^{2}

Step-by-step explanation:

we know that

The area of the circle is equal to

A=\pi r^{2}

we have

r=6/2=3\ units ----> the radius is half the diameter

substitute

A=\pi (3)^{2}=9 \pi\ units^{2} -----> exact value

assume

\pi=3.14

A=9(3.14)=28.26\ units^{2}

tamaranim1 [39]

Answer: the bridge is 11.025 m high

Step-by-step explanation:

Given that;

Time taken to hit the water t = 1.5 sec

height of bridge = ?

lets take a look at the equation of motion;

y(t) = y₀ + (1/2)at²

with initial velocity zero and we know that acceleration due to gravidity is 9.8m/s

we substitute

y(t) = (1/2)gt² = (1/2) × 9.8 × (1.5)²

y(t) = (1/2)gt² = (1/2) × 9.8 × (1.5)²

y(1.5) = 11.025 m

Therefore, the bridge is 11.025 m high
