The volume of the sphere is 288 \pi cubic meters.

Explanation:

Given that the radius of the sphere is 6 m

We need to determine the volume of the sphere.

<u>Volume of the sphere:</u>

The volume of the sphere can be determined using the formula,

V=\frac{4}{3} \pi r^{3}

Substituting the value r=6 in the above formula, we have,

V=\frac{4}{3} \pi (6)^{3}

Simplifying the values, we get,

V=\frac{4}{3} \pi (216)

V=\frac{864}{3} \pi

V=288 \pi

Thus, the volume of the sphere is 288 \pi cubic meters.

Answer:

1. 38, 80, 89 and 4. 14, 15, 29

I don't know if there is supposed to be only one, but both of those do not form right triangles.

Step-by-step explanation:

Evaluate all of them and see if they meet the requirements of the Pythagorean Theorem, a² + b² = c².

1. 38, 80, 89

a² + b² = c²

38² + 80² = 89²

1444 + 6400 = 7921

7844 ≠ 7921.

This is an answer because it doesn't satisfy the Pythagorean Theorem.

2. 16, 63, 65

a² + b² = c²

16² + 63² = 65²

256 + 3969 = 4225

4225 = 4225

This isn't the answer because it satisfies the Pythagorean Theorem.

3. 36, 77, 85

a² + b² = c²

36² + 77² = 85²

1296 + 5929 = 7225

7225 = 7225

This isn't the answer because it satisfies the Pythagorean Theorem.

4. 14, 15, 29

a² + b² = c²

14² + 15² = 29²

196 + 225 = 841

421 ≠ 841

This is an answer because it does not satisfy the Pythagorean Theorem.

35r−21&lt;−35r+19 solve for r
topjm [15]

Answer:r<4/7

Step-by-step explanation:

35r-21<-35r+19

Collect like terms

35r+35r<21+19

70r<40

divide both sides by 70

70r/70<40/70

r<40/70

r<4/7
