Mathematics

Answer:

Simplify the problems first

Step-by-step explanation:

Before you can convert it to scientific notation, you should simplify it first.

#1 for example:

(4 \times 10^5)^2\\

Use PEMDAS to solve the equation:

(4 \times 10^5)^2\\= 400000^2\\= 160000000000

So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be  1.6 \times 10^{11} since there are 11 places after the decimal.

Help me solve the volume for the sphere?
iogann1982 [59]

Answer:

38.77 yd³

Step-by-step explanation:

The volume of the sphere can be determined by using the formula 4πr³/3.

[Where "r" is the radius of the circle].

<u>We are given that:</u>

Radius of circle = 2.1 yd

<u />

<u>When we substitute the radius in the formula, we get;</u>

⇒ 4 × π × (2.1)³/3

<u>Let π be substituted as 3.14. Then;</u>

⇒ 4 × π × (2.1)³/3

⇒ 4 × (3.14) × (2.1)³/3

<u>When evaulating the cube of 2.1, we get;</u>

⇒ 4 × (3.14) × (2.1)³/3

⇒ 4 × (3.14) × (2.1) × (2.1) × (2.1)/3

<u>When simplified, we get;</u>

⇒ 4 × (3.14) × (2.1) × (2.1) × (2.1)/3

⇒ 4 × (3.14) × (2.1) × (2.1) × (0.7)

⇒ 4 × (3.14) × (4.41) × (0.7)

⇒ (12.56) × (4.41) × (0.7)

⇒ 38.77272 ≈ 38.77 yd³          (Rounded to nearest hundredth)    

Therefore, the volume of the sphere is 38.77 yd³.
