Marcus wants to decorate his box that is i the shape of a cube with a color. he decides to cover the entire box with red color p

olga2289 [7]

*see attached picture for the diagram of the box

Answer:

130cm²

Step-by-step explanation

The amount of red appear needed by Marcus to cover his box = Surface Area of the cube - Area of the circle.

Surface area of cube = 6s² (where s is the side length of the cube. s² therefore is S.A of 1 face of the cube)

Given that s = 5cm,

S.A of cube = 6s² = 6*5² = 150cm²

Area of circle = πr²;

Given that π = 3.14, and r = ½ of diameter of circle (i.e. ½ of side length of cube)

Area of circle = 3.14*(½*5)² = 3.14*(2.5)² = 3.14*6.25 =19.625

Amount of red paper needed = S.A of the cube - Area of the circle = 150cm² - 19.625cm² = 130.375cm² = 130cm²

As of right now, Katie’s college fund has $601.85. If she deposits a check for $225, how much money will she have in her college

sashaice [31]

I’m pretty sure it’s $826.85 because deposit means to put money into something. So, you’d just add $601.85 to $225 to get your answer. I think.

Find mZAEB A 38° B 66° 47° 859

Norma-Jean [14]

Answer:

$85\degree$

Step-by-step explanation:

By the property of intersecting chords inside a circle.

$m\angle AEB=\frac{1}{2} (132\degree + 38\degree)$

$m\angle AEB=\frac{1}{2} \times 170\degree$

$m\angle AEB=85\degree$
