How to find perimeter of semicircle​

Mathematics
1 answer:
Arlecino [84]4 years ago
5 0

Answer:

1/2 π × d + d where d is the diagonal

Step-by-step explanation:

The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle you need to go half way around the circle and then across a diagonal to get back to where you started so the perimeter is 1/2 π × d + d.

nekit [7.7K]

Answer:

See Explanation

Step-by-step explanation:

Given

Weight = 41.3kg

Required

Determine the weights that approximates to 41.3kg

The options are not given but the question is still solvable

In approximation:

0 - 4 approximates to 0

This implies that:

41.30 to 41.34 approximates to 41.3

Also:

5 - 9 approximates to 1

This implies that:

41.25 to 41.29 approximates to 41.3

Bring the range together, we have:

Range = 41.25\ to\ 41.34

<em>Select any three numbers within this range, and you have your answer</em>

Examples are: <em>41.25, 41.28, 41.34</em>\

Write the equation of the line that goes through the point (6,-4) and is parallel to y = -x + 1. 1 3
omeli [17]

9514 1404 393

Answer:

  y = -x +2

Step-by-step explanation:

The parallel line will have the same slope; only the constant will be different. We can find that constant using the given point.

  y = -x +b

  -4 = -6 + b . . . substitute for x and y

  2 = b . . . . . . add 6

The desired equation is ...

  y = -x +2
