Vikki [24]
To find whether the volume would be doubled when the radius is,we can find the volume of the two balloons.

The formula of a sphere is:
\frac{4}{3} \pi \: {r}^{3}
Let's take 丌 as 3.14

The volume of the balloon with 4cm radius:
\frac{4}{3}(3.14)  \times  {4}^{3}  \\  = 4.18667 \times 64 \\  = 267.94688

The volume of the balloon with 8cm radius:
\frac{4}{3}(3.14)  \times  {8}^{3}  \\  = 4.18667 \times 512 \\  = 2143.57504
As we can see,
267.94668 × 2 = 535.89 ≠2145.56

Thus,she wouldn't discover that the volume is twice as big when the radius is doubled.

Hope it helps!

Andrew [12]

The two events that created the most tension in the story include:

  • Mrs. White suggests that her husband wishes for four hands for her.
  • Mr. White paid Sergeant-Major Morris a trifle for the paw.

<h3>What is tension?</h3>

It should be noted that tension in literature simply means the sense of something ominous in the literary work. It's a feeling that something is about to happen.

The Monkey's Paw is a horror short story by author W. W. Jacobs. In the story, three wishes are granted to the owner of The Monkey's Paw, but the wishes come with a price for interfering with fate.

It should be noted that Mrs. White suggesting that her husband wish for four hands for her created tension in the story as the readers were eager to know what happened in the story. Also, it should be noted Mr. White paying Sergeant-Major Morris a trifle for the paw created tension.
