A cube whose edge is 20 cm 1 point

Sav [38]

Answer:

Unpainted surface area = 514.28 cm²

Step-by-step explanation:

Given:

Side of cube = 20 Cm

Radius of circle = 20 / 2 = 10 Cm

Find:

Unpainted surface area

Computation:

Unpainted surface area = Surface area of cube - 6(Area of circle)

Unpainted surface area = 6a² - 6[πr²]

Unpainted surface area = 6[a² - πr²]

Unpainted surface area = 6[20² - π10²]

Unpainted surface area = 6[400 - 314.285714]

Unpainted surface area = 514.28 cm²

Simplify the following expression. 4a^-2b A.) b/4a^2 B.)4b/a^2 C.)1/4a^b2

Sergio [31]

ANSWER

The correct answer is B

$\frac{4b}{ {a}^{2} }$

EXPLANATION

The given exponential expression is

$4 {a}^{ - 2} b$

We can rewrite this as,

$4b \times {a}^{ - 2}$

We need to simplify to obtain a positive index, so we apply the following property,

${a}^{ - m} = \frac{1}{ {a}^{m} }$

This implies that,

$4b \times {a}^{ - 2} = 4b \times \frac{1}{ {a}^{2} }$

This will finally simplify to,

$4b \times {a}^{ - 2} =\frac{4b}{ {a}^{2} }$

Therefore the correct answer is B
