Answer:

-5-\sqrt{-44}=-5-2\sqrt{11}i

Step-by-step explanation:

We want to simplify:

-5-\sqrt{-44}

We rewrite the expression under the radical sign to obtain:

-5-\sqrt{4\times11\times -1}

We split the expression under the radical sign to get:

-5-\sqrt{4} \times \sqrt{11} \times \sqrt{-1}

Recall that:

\sqrt{-1}=i

This implies that:

-5-\sqrt{4} \times \sqrt{11} \times \sqrt{-1}=-5-2\sqrt{11}i

Therefore -5-\sqrt{-44}=-5-2\sqrt{11}i

The circumference of the hub cap of a tire is 83.96 centimeters. Find the area of this hub cap. Use 3.14 for . Use pencil and pa
Bess [88]

Answer:

Area = 561.2485 square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.

Step-by-step explanation:

As we know the circumference of a circle is 2\pi r

The radius of the hub cap needs to be devised to determine the area

83.96 = 2* 3.14*r

r = \frac{83.96}{2*3.14}

r = 13.37 centimeters

Area of the hub cap = \pi r^{2}

Substituting the devised value of r in the above equation, we get -

3.14 * 13.37^2\\

561.2485 square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
