Identify the volume and surface area of the sphere in terms of π. HELP PLEASE!!

Helen [10]

Answer:

First choice V = 18,432π m^3; S = 2,304π m^2

Step-by-step explanation:

Start with the two formulas:

Volume of a circle:

$V = \dfrac{4}{3} \pi r^3$

Surface area of a circle:

$S = 4 \pi r^2$

Now use r = 24 m in each formula.

Volume:

$V = \dfrac{4}{3} \pi (24~m)^3$

$V = \dfrac{4}{3} \pi (13,824~m^3)$

$V = 18,432\pi~m^3$

Surface area:

$S = 4 \pi r^2$

$S = 4 \pi (24~m)^2$

$S = 4 \pi (576~m^2)$

$S = 2,304\pi ~m^2$

Answer: First choice V = 18,432π m^3; S = 2,304π m^2

(3x^2a - 4y^a z^3a) ^2 ...?

shusha [124]

The answer is 9x⁴ᵃ - 24x²ᵃyᵃz³ᵃ + 16 y²ᵃz⁶ᵃ

(a - b)² = a² - 2ab + b²
(3x²ᵃ - 4yᵃz³ᵃ)² = (3x²ᵃ)² - 2 * 3x²ᵃ * 4yᵃz³ᵃ + (4yᵃz³ᵃ)² =
= 3²x²ᵃ*² - 2 * 3 * 4 x²ᵃ * yᵃz³ᵃ + 4²yᵃ*²z³ᵃ*² =
= 9x⁴ᵃ - 24x²ᵃyᵃz³ᵃ + 16 y²ᵃz⁶ᵃ
