Gemiola [76]

Answer:

Step-by-step explanation:

volume=πr^2h

461.58=3.14*r^2*12

461.58=37.68*r^2

461.58/37.68=r^2

12.25=r^2

\sqrt{12.25=r

3.5=r

diameter=radius*2

=3.5*2

=7 in.

Use the law of cosines to write an expression equivalent to b
andrezito [222]

Given:

A triangle ABC.

The given expression for b is:

b=\sqrt{m+n-pq}

To find:

The expression that is equivalent to b.

Solution:

According to the Law of Cosines,

b^2=a^2+c^2-2ac\cos B

It can be written as:

b=\sqrt{a^2+c^2-2ac\cos B}              ...(i)

We have,

b=\sqrt{m+n-pq}                                ...(ii)

On comparing (i) and (ii), we get

m=a^2

n=c^2

p=2ac

q=\cos B

Therefore, the required values are m=a^2,n=c^2,p=2ac,q=\cos B.
