Answer:

the answer is A 579m/s

Step-by-step explanation:

Given,

v=?    u=3m/s a=4m/s^2 and  t=72

Now,

v=u+2at

=3+2{4(72)}

= 3+2(288)

=3+576

=579m/s

a circular mirror is surrounded by a square metal frame. the radius of the mirror is 2x. the side length of the metal frame is 1
nasty-shy [4]

The area of the metal frame is 87.43x^2 sq. units.

Solution:

A circular mirror is surrounded by a square metal frame.

Radius of the circular mirror = 2x

Side length of the square frame = 10x

To find the area of the metal frame.

Area of the square frame = Side × Side

                                        = 10x \times 10x

                                        = 100x^2 sq. units

Area of the square metal frame = 4x^2  sq. units

Area of the circular mirror = \pi r^2

                                         = \frac{22}{7}\times(2x)^2  

                                         = 12.57 x^2 sq. units

Area of the circular mirror = 12.57 x^2 sq. units

Area of the metal frame = Area of the square frame – Area of the mirror

                                      = 100x^2-12.57 x^2

                                      = 87.43x^2 sq. units

Hence the area of the metal frame is 87.43x^2 sq. units.
