Point-slope form: y - y₁ = m(x - x₁)

(m is the slope, (x₁, y₁) is the point you are given that is on the line)

You know:

m = 5

(x₁, y₁) = (-2, -3) So substitute/plug it into the equation

y - y₁ = m(x - x₁)

y - (-3) = 5(x - (-2)) (two negative signs cancel each other out and become positive)

y + 3 = 5(x + 2) Your answer is A

The radius of a circular plate is 12 centimeters. What is the area, in square centimeters, of this plate? Write your Anwer using

lesya [120]

Answer:

The area of circular plate is <u>144π square centimeters</u>.

Step-by-step explanation :

<h3><u>Solution</u> :</h3>

Here, we have given that the radius of circular plate is 12 centimeters.

So, finding the area of circular plate by substituting the values in the formula :

$\longrightarrow{\pmb{\sf{Area_{(Circle)} = \pi{r}^{2}}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12)}^{2}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12 \times 12)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(144)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi \times 144}}$

$\longrightarrow{\sf{Area_{(Circle)} = 144\pi}}$

$\star{\underline{\boxed{\frak{\purple{Area_{(Circle)} = 144\pi\: {cm}^{2}}}}}}$

Hence, the area of circular plate is 144π square centimeters.
