Find the CIRCUMFERENCE of a circle with a RADIUS of 13mm. Use 3.14 for the value of pi.

Answers

Answer:

Circumference = 81.64

Step-by-step explanation:

The formula for finding circumference is C = pi(d). Since you don't have the diameter, but you do have the radius (which is half of the diameter), you will multiply 13 by 2, or 13 x 2. 13 x 2 = 26. So, the diameter is 26.

Fill in what you know: C = 3.14(26)

Now, all you have to do is multiply 3.14 and 26, which equals 81.64.

Hope this helps! :)

For finding circumference you want to double the radius first to get a diameter. 13mm*2= 26mm so the diameter is 26 now we need to multiply it by 3.14 (the first 3 digits of pi). 26mm*3.14= 81.64mm Hope this helped!!

Answers

Answer:

28.3

Step-by-step explanation:

Answer:

28.3

Step-by-step explanation:

Use the Pythagorean theorem a^2 + b^2 = c^2

x is a, 17 is b, and 33 is c

x^2 + 17^2 = 33^2

Simplify:

x^2 + 289 = 1089

Subtract 289 from both sides:

x^2 = 800

Square root both sides:

x = √800

√800 is 28.28427, or 28.3

Explain why you divide by 2 for triangles and why you divide by 3 for pyramids

Answers

Answer:

triangles are half a rectangle/square. So thats why you divide by 2. diving by 2 is also multiply by 1/2.

pyramids are in 3 dimensions, so since they are like half, but in three dimensions, you divide by 3, in other words multiply by 1/3.

QUESTION 2

The owner of a small restaurant bought 75 kilograms of rice. Each week, the restaurant uses 4.5 kilograms of rice.



Function `r` gives the remaining amount of rice, in kilograms, as a function of the number of weeks since the restaurant owner bought the rice.



Solve the equation `r(w)=30`and explain what the solution means in this situation.

Answers

Answer:

r(t) = 75 kg - (4.5 kg/wk)w

Step-by-step explanation:

Let r(t) represent the amount of rice remaining after w weeks.

Then:

r(t) = 75 kg - (4.5 kg/wk)w

please mark as brainliest

Answer:

w=10 and this means that 10 weeks after the rice was bought, 30 kilograms of rice remain.

Step-by-step explanation:

r(w)=75-4.5w is an equation for this function so I'll be using this. First insert r(w)= 30 into the equation.

75-4.5w=30

75-75-4.5w=30-75

-4.5w=-45

-4.5w/-4.5 = -45/ -4.5

w=10

Apologies if the explanation isn't thorough, I'll glady provide more details if necessary.
