So the formula to find the area of a circle is A = pie x r or (radius)^2 so the radius is just squared.
so the radius of the circle is 3 so you would square that.
pie is 3.14(rounded)
A = 3.14(pie) x 3^2
A = 3.14 x 9
A = 28.26
my calculator got that which is different from the other person's answer but i hope this will help you!

The points (8,0) and (-8,c) fall on a line with a slope of 1/8. What is the value of c?<br> c=
Anna007 [38]

Answer:

c = - 2

Step-by-step explanation:

calculate the slope m using the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (8, 0) and (x₂, y₂ ) = (- 8, c)

m = \frac{c-0}{-8-8} = \frac{c}{-16} = \frac{1}{8}

cross- multiplying gives

8c = - 16 ( divide both sides by 2 )

c = - 2

vredina [299]

Answer:

5×10⁻²

Step-by-step explanation:

  • Move the decimal so there is one non-zero digit to the left of the decimal point.
  • The number of decimal places you move will be the exponent on the 10. a.  If the decimal is being moved to the right, the exponent will be negative.

        b.  If the decimal is being moved to the left, the exponent will be positive.

  • Therefore. The answer is 5×10⁻²
