What is the approximate volume of a basketball with the circumference of 42ft ?

Mathematics
1 answer:
Semmy [17]3 years ago
4 0
We know that

[volume of a sphere]=(4/3)*pi*r³

length of a circumference=42 ft
[length of a circumference]=2*pi*r-------> r=[length of a circumference]/(2*pi)
r=[42]/(2*pi)---------> r=6.6845 ft

[volume of a sphere]=(4/3)*pi*6.6845³-----------> 1251.11 ft³

the answer is 1251.11 ft³

Help i give 5 stars and a crown​
REY [17]

Answer:

See below.

Step-by-step explanation:

1a)

<u>Angles:</u>

  • 48, 90, 90, a.

<u>Add:</u>

  • 48 + 90
  • = 138 + 90
  • = 228

<u>Subtract:</u>

  • 360 - 228
  • = 132.

Angle a: 132.

1b)

To get angle h above 180°, <u>We need to add h + 164:</u>

  • h + 164
  • = 110 + 164
  • = 274.

h = 110.

This is how to get h over 180°.

sveticcg [70]
This is a relatively simple half life calculation.
To go from 6 to 3 grams, 1622 years is required.
3 to 1.5 grams another 1622 years is required.
So, it undergoes exactly 2 half-lives or 3,244 years.
