A150 cm pendulum swings through an arc which measured 100pi cm. in exact radians, through what angle does it swing?

Pendulum will swing by an angle 0.666π

Step-by-step explanation:

We have given arc =

And length of the pendulum l = 150 cm

Length of the pendulum will be equal to radius of the pendulum so r = 150 cm

Arc is given by

So

So pendulum will swing by an angle 0.666π

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..
