What is the exact circumference of a circle that has a radius of 10 cm?

Answers

Answer 1

Answer:

C = 20π cm

Step-by-step explanation:

If you want the "exact circumference," use π instead of the usual approximation 3.14 or 3.14159.

Here the circumference is C = 2π(10 cm), or C = 20π cm.

Answer 2
The exact circumference is 62.83 cm.

Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1

so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)

An art teacher makes a batch of purple paint by mixing 3/4 cup red paint with 3/4 cup of blue paint. If she mikes 13 batches, how many cups of purple paint will she have?

Answers

She will have 19.5 cups of purple paint.
I couldn’t write the explanation of how you get the answer, but look your question up on Brainly and it’ll give you your explanation.

Hope this helped! :)

Answer:

She will have 19 ¹/₂ batches of purple paint

Step-by-step explanation:

r + b = 1 bp

³/₄ r + ³/₄ b = 1 bp

(³/₄ + ³/₄) * 13 = x bp

⁶/₄ = 1 ¹/₂

1 ¹/₂ * 13 = 13 ¹³/₂ = 19 ¹/₂ batches

VARIABLE KEY:

r = red

b = blue

bp = batches of purple

x = total number of bp

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.

Answers

Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

Diameter is a line that goes through a circle. Radius is a line that goes from the edge of the circle all the way to the center/a line that goes halfway through the circle.

--------------------------------------------------------------------------------------------------------------

First, find the area of the circle. Here is the formula:

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

Then, you just do the math:

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.

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
