2. TOYS A playground ball has a radius of

dalvyx [7]

Answer:

1767.1 inches cubed

Step-by-step explanation:

The volume of a ball, or a sphere, is: $V=\frac{4}{3} \pi r^3$ , where r is the radius.

Here, the radius is r = 7.5. So, plug in this value: $V=\frac{4}{3} \pi *(7.5)^3=562.5\pi$

562.5 pi is about 1767.1 inches cubed.

Thus, the volume is 1767.1 inches cubed.

Hope this helps!

If 5x – 4 = 31, what is the value of x?

Lunna [17]

Answer:

x = 5 $\frac{2}{5}$

Step-by-step explanation:

Hi there!

So, to answer this problem, I'll use the reverse method.

31 - 4 = 27,

So how many times, can 5 go into 27?

The closest factor of 5 to 27 is 25.

5 can go in to 27, 5 times.

Continuing on, there is a 2 left over, so the answer to your question is

x = 5 $\frac{2}{5}$

5 · 5 $\frac{2}{5}$ - 4 = 31

Let me know if I am incorrect and I will attempt to find the right answer for you.

Find the measure someone please help

Ierofanga [76]

Answer:

m∠B = 31°

Step-by-step explanation:

First, find the measure of angle ACB by subtracting its supplement from 180 degrees:

180 - 113 = 77

m∠ACB = 77°

Then subtract both m∠A and m∠ACB from 180 degrees, since the interior angles of a triangle always add to 180°:

m∠B = 180° - 72° - 77°

m∠B = 31°
