zalisa [80]

Answer:

The radius of the circle is 9 in

Choice C is correct

Step-by-step explanation:

254.4696 square inches. Whats the radius of the circle (use pie=3.1416.

The area of a circle with radius r is given as;

$A=\pi *r^{2}$

We substitute the given area and the value of pi given to solve for the radius;

$254.4696=3.1416*r^{2}\\\\r^{2}=\frac{254.4696}{3.1416}\\\\r^{2}=81\\\\r=\sqrt{81}=9\\\\r=9$

5(wx-v)=9(x+v) make x the subject

Zepler [3.9K]

Expand the brackets first
5(wx-v) = 9(x + v)
5wx - 5v = 9x + 9v

Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v

factorise out the x
x(9-5w) = 14v

then divide by 9-5w
x = 14v/(9-5w)
