Answer:

1149.8 m³

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = $\frac{4}{3}$ πr³ ( r is the radius )

Here diameter = 13, thus radius = 13 ÷ 2 = 6.5

V = $\frac{4}{3}$ × 3.14 × 6.5³

= $\frac{4}{3}$ × 3.14 × 274.625

= $\frac{4(3.14)(274.625)}{3}$ ≈ 1149.8 m³ ( to the nearest tenth )

Simplify. [6.6 ÷ (–5 + 3)] • (–1)

eimsori [14]

Hi there, we use PEMDAS to solve this problem, PEMDAS is parenthesis, Exponents, Multiply, Divide, Add, and Subtract. In this case, we have [6.6÷(-5+3)]*(-1), 6.6/-5+3(-1)=6.6/-2(-1)=(-3.3)(-1)=3.3. So, your answer is 3.3

Irrational number between 2/7 and 3/7

e-lub [12.9K]

Answer: pi/8

Step-by-step explanation:

adding or multiplying an irrational by a rational will result in another irrational. So we could take something like pi and divide it until it’s between 2/7 and 3/7. I did that and apparently pi/8 works, so boom
