What is perimeter of the semi circle?

Nesterboy [21]

Answer:

54.22 mm

Step-by-step explanation:

Find the circumference of the circle and then divide it by 2.

We start with the formula for the circumference for the circle:

C = 2πr

To find r, divide 22 by 2:

22/2=11

Now find the cicumference:

C = 2πr = 2(3.14)(11) = 108.46 mm

NOW, to find the perimeter of the semicircle, divide the circumference by 2:

108.46/2 = 54.22 mm

Which lines are perpendicular?

makkiz [27]

Given:

Line A: $y=\frac{1}{2} x+2$

Line B: $y=\frac{-1}{2} x+7$

Line C: $y=2 x+4$

Line D: $y=\frac{1}{2} x+\frac{5}{4}$

To find:

Which lines are perpendicular

Solution:

General equation of a line:

y = mx + c

where m is the slope and c is the y-intercept.

Slope of line A = $\frac{1}{2}$

Slope of line B = $\frac{-1}{2}$

Slope of line C = 2

Slope of line D = $\frac{1}{2}$

<em>Two lines are perpendicular if their slopes are negative reciprocal of one another.</em>

$$\Rightarrow m_1=\frac{-1}{m_2}$

$$\frac{-1}{2}=-(-2)=2$

Negative reciprocal of $\frac{-1}{2}$ is 2.

Therefore line B and line C are perpendicular lines.

Shannon swims one fourth of the total rent in cycles three-fifths the remaining route she runs the rest of the route if she runs

Alina [70]

This question is intriguing. Shannon does something that involves
the rent, a route, and a rope. I'm having serious difficulty trying to
understand how these are related.
