Step-by-step explanation:

r≈3.5m

C Circumference

Using the formula

C=2πr

Solving forr

r=C

2π=22

2·π≈3.50141m

Approximately

3.5

Explanation:

The circumference of a circle C is equal to:

⋅

That's because the diameter of a circle fits

times in the circumference. So if you solve

⋅

≈

What is the point slope of the line when slope is -4 and the given coordinates are (4,-9)

Lina20 [59]

The point-slope form of the equation of a straight line is:

$y-y_1=m(x-x_1)$

We have:

$m=-4\\(4;-9)\to x_1=4;\ y_1=-9$

Substitute:

$y-(-9)=-4(x-4)\\\\\boxed{y+9=-4(x-4)}$

Lola's hockey team lost 15% of

MAVERICK [17]

Answer:

$20$

Step-by-step explanation:

Let $x$ = games played in total

From the fact that $15\%$ of the games the team played is equivalent to $3$ games, we can write:

$15\%x = 3$

$x=3\div 15\%$

$=20$

∴ Lola's hockey team played a total of 20 games.

Hope this helps :)
