Answer:

210.25 or 210.3495409 depending on how your teacher does it

Step-by-step explanation:

Looking for circumference of the circle when it asks for perimeter

Formula for Circumference C = π x r <em>3 (cubed)</em>

The diameter is 10 so you take half of ten or 10 ÷ 2 = 5

5 x 5 x 5 = 125 (r squared equation)

125 x π = 392.6990817

Some classes ans stuff use 3.14 for pi so i'll show it that way too

125 x 3.14 = 392.5

(equation with π)

392.6990817 ÷ 2 = 196.3495409

196.3495409 + 14 = 210.3495409

(equation with 3.14)

392.5 ÷ 2 = 196.25

14 + 196.25 = 210.25

Write the equation of a line that is parallel to y = 7x +13 that passes through the point (28, 8).

navik [9.2K]

Answer:

y=7x-188

Step-by-step explanation:

We know that this line must have a slope of 7, because this line is parallel to y=7x+13

We must use the point slope formula: y- $y_{1}$ = m(x- $x_{1}$ )

Next, we will plug in the point (28,8) for $y_{1}$ and $x_{1}$ , and 7 in for m

y-8=7(x-28)

Solve the equation, first by distributing the 7

y-8=7x-196

Add the 8 over

y=7x-188
