Shalnov [3]

Answer: 25%

Step-by-step explanation:

Given

Emelia measures the weight of the rock to be 30 gm

The actual weight was 24 gm

Percentage error is given by

$\Rightarrow \dfrac{\text{Deviation }}{\text{Actual value}}\times 100$

Insert the values

$\Rightarrow \dfrac{30-24}{24}\times 100\\\\\Rightarrow \dfrac{6}{24}\times 100\\\\\Rightarrow 25\%$

Therefore, the percentage error is 25%.

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
