Answer:

$-15$

Step-by-step explanation:

We can factor out a 1 from -3 to get $5\cdot(-3)=5\cdot-1\cdot3=-1(5\cdot3)$ .

We know from simple arithmetic that $5\cdot3=5+5+5=10+5=15$ .

So, our answer is $-1(15)=\boxed{-15}$

Answer:

r = 5 inches

Step-by-step explanation:

Area of circle, $A=78.5\ in^2$

It is required to find the radius of the circle. The area of a circle is given by the formula :

$A=\pi r^2$

r is radius of the circle

$r=\sqrt{\dfrac{A}{\pi}} \\\\r=\sqrt{\dfrac{78.5}{3.14}} \\\\r=5\ \text{inch}$

So, the radius of the circle is 5 inches.
