It would take him 180 mins or 3 hours.

This is because it takes him for 2 minutes to make 1 donut.

So 90 x 2 = 180 minutes or 3 hours.

If the circumference of the circle is 37.68 units, what is the area? (Use 3.14 for pi .)
cricket20 [7]

Answer:

Area of the circle = 113.04\;units^2

Step-by-step explanation:

Circumference = 37.68\;units

Circumference of the circle = 2\times \pi  \times r

As,

    \pi =\dfrac{22}{7}=3.14

                        37.68=2\times \pi  \times r\\\\37.68=2\times 3.14 \times r\\\\37.68=6.28\times r\\\\r=\dfrac{37.68}{6.28} \\\\r=6\;units

Area of a circle = \pi \times r^2

                       =3.14\times (6\times 6)\\\\=3.14\times 36\\\\=113.04\;units^2

Find the Range and Domain of the Binary relations
sukhopar [10]

Answer:

A = {3,5,6}

B = {1,3}

<u><em>A x B</em></u> = {(3,1),(3,3),(5,1),(5,3),(6,1),(6,3)}

Domain of A x B = (The x figures in ascending order)

=> {3,5,6}     (Figures repeating more than once must be written only 1 time)

Range of A x B = (The y figures in ascending order)

=> {1,3}

<u><em>B x A </em></u>= {(1,3),(3,3),(1,5),(3,5),(1,6),(3,6)}

Domain of B x A = {1,3}

Range of A x B = {3,5,6}
