When paid flat a round parachute has a diameter of 8 meters. What is the parachute’s circumference
mariarad [96]

Answer:

25.12 meters

Step-by-step explanation:

The circumference of a circle is given by

c=2\pi r (1)

where:

\pi\sim 3.14

r is the radius of the circle

In this problem, the parachute has a diameter of 8 meters:

d = 8 m

The radius of a circle is equal to half of its diameter, so the radius of the parachute is:

r=\frac{d}{2}=\frac{8}{2}=4 m

And therefore, by applying eq.(1) we can find the circumference of the circle:

c=2\pi r=2\cdot 3.14 \cdot 4 = 25.12 m

Amanda used 24 grams of paint to paint a wooden cube. When it dried, she cut the cube into 8 equal cubes. How many more grams of
kari74 [83]

Answer:

<h2>Amanda needs 72 grams of paint</h2>

Step-by-step explanation:

Notice that she already painted one face of each cube, that is, 8 faces in total, and she used 24 grams for that.

Now, there remain 3 faces per cube to be painted, which means there are 24 faces.

Then, we use the rule of three, if she used 24 grams of paint for 8 faces, how much grams of paint she would need to paint 24 faces?

24 \times \frac{24}{8}= 72 \ grams

Therefore, Amanda needs 72 grams of paint for the unpainted surfaces.
