A circle has a diameter of 14cm. What's the circumfrence?
vesna_86 [32]
I believe that when finding the radius of a circle you half the diameter, but when finding the circumference of a circle you need to multiply the diameter (14cm) by pi.

So 14xpi= 43.98229715

But it can be simplified/ rounded to 44cm.

Of course I might be incorrect so do please correct me if I am wrong.

If u = -8i + 7j, what is the magnitude of -5u? Simplify any radicals.​
lubasha [3.4K]

Answer:

- 5 \sqrt{113}

Step-by-step explanation:

Find the magnitude of the complex number

Notice the magnitude is equal to

u = \sqrt{ {a}^{2}  +  {b}^{2} }

where a is the real number and b is the imaginary number.

Substitute

u =  \sqrt{ - 8 {}^{2}  + 7 {}^{2} }

u =  \sqrt{64 + 49}

u =  \sqrt{113}

Multiply this by -5

- 5 \sqrt{113}
