Area of a circle is found using the formula: A = PI x r^2 where r is the radius of the circle, which is half the diameter.

Using the information in the problem you have:

A= PI x 15^2

A = PI x 225

A = 706.5 sq. In.

Answer:

A =706.5 in^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

We are given the diameter

r = d/2  = 30/2 = 15

A = pi * 15^2

A = pi*225

We can approximate pi by 3.14

A = (3.14)*225

A =706.5 in^2

Lady bird [3.3K]

Answer:

m=\frac{-1}{2}

Step-by-step explanation:

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>:

m=\frac{-3-(-1)}{2-(-2)}

m=\frac{-3+1}{2+2}

m=\frac{-2}{4}

m=\frac{-1}{2}

Answer:

y = -1/4x -2

Step-by-step explanation:

the perpendicular slope would be -1/4

2 = -1/4 (-16) + b

b = -2

the equation should be y = -1/4x -2
