A spherical boulder is 18 ft in diameter and weighs almost 8 tons. Find the volume. Use 3.14 for piπ.

vampirchik [111]

Answer:

Volume, $V=3052.08\ ft^3$

Step-by-step explanation:

It is given that,

Diameter of spherical boulder is 18 ft

Weight of spherical boulder is 8 tons.

We need to find the volume of spherical boulder. The formula of the volume of sphere is given by :

$V=\dfrac{4}{3}\pi r^3$

r is radius of spherical boulder, r = 9 ft

Substituting all values in above formula :

$V=\dfrac{4}{3}\times 3.14\times (9)^3\\\\V=3052.08\ ft^3$

The volume of spherical boulder is $3052.08\ ft^3$ .

Megan was painting on a rectangular canvas, and needed a frame for it. The length of the frame is 15 inches and the width is 10

siniylev [52]

Answer:

50 inches

Step-by-step explanation:

Hi there!

$P=2l+2w$ where l is the length of the rectangle and w is the width of the rectangle

Plug in the length (15 inches) and width (10 inches)

$P=2(15)+2(10)\\P=30+20\\P=50$

Therefore, the perimeter of the frame is 50 inches.

I hope this helps!

A number k is greater than 3. Which of the following is true about 승 ? 1 It is between 3 3 It is equal to 1 It is greater than 1

Alekssandra [29.7K]

If the number k is greater than 3, we have the following inequality:

$k>3$

In order to evaluate k/3, let's divide the inequality by 3:

$\begin{gathered} k>3 \\ \frac{k}{3}>\frac{3}{3} \\ \frac{k}{3}>1 \end{gathered}$

So the expression k/3 is greater than 1, therefore the correct option is D.
