If you used π, 157.079632679 yards or 157.08 yards rounded to the hundredths place. If you used 3.14, the answer is 157 yards.

Step-by-step explanation:

The formula to find the perimeter of a circle is P=2×π×r.

Step 1: Find the radius. In this case, the radius is 25 yards as shown in the diagram.

Step 2: Since the formula only includes multiplication, you can multiply any of the factors. For simplicity, multiply your radius by 2 first. In this case, 2×25=50.

Step 3: Multiply your last number with π. In this case, 50×π=157.079632679 or 157.08 rounded the hundredths place. 50×3.14=157.

Step 4: You found the answer! Hope this helps.

Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles  )

∠ ABC = 87°

Step-by-step explanation:

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s eyes to be 1 times as far apart as Dan’s eyes. A scale giant would have the same multiple for both.

If Dan's eyes are 5 cm apart, how many centimeters apart should Marcellus's eyes be?

Answers

If you dragged Marcellus’s eyes apart 1x farther than Dan’s eyes then they would both have eyes that are 5cm apart because 5 x 1 = 5

Marcellus's eyes should be 5 cm apart

If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;

Marcellus eyes are 1x far apart as Dan's eyes.

If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.

Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.

Essentially, Marcellus's eyes will be just as wide as Dan's eyes
