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 paper except the circular window, shown with his name on it. the box is show. rounded to nearest square centimeter, how much red paper is needed to cover Marcus box ? Marcus uses 3.14 to estimate pi

*see attached picture for the diagram of the box

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

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
