The circumference of the top rim of the cone shaped paper cut is 7.87 inches. Find the least amount of paper that can for a cone

Montano1993 [528]

Answer:

14.55 square inches

Step-by-step explanation:

From the figure it is given that,

The circumference of the top rim of a cone shaped paper cut = 2πr = 7.87 inches

The slant height is l = 3.7 inch

Therefore the least amount of paper which can form a cone shaped cup is the surface area of the cone.

The surface area of the cone is given as :

$A=\frac{2 \pi r l}{2}$

$A=\frac{(2 \pi r) (l)}{2}$

$A = \frac{(7.87) \times (3.7)}{2}$

$A=\frac{29.119}{2}$

A = 14.55 square inches

Amount of paper required = 14.55 square inches

Which equation is represented by the table? a) y=|x-4| b) y=|x|-4 c) y=|x|+4 d) y=|x+4|

wariber [46]

Answer:

option (a) y=|x-4| is correct.

Step-by-step explanation:

Solve the question by elimination method i.e. put values of x in the given equations and check if equality holds.

(b) if x=2, then y= |2| - 4 = -2 , which is wrong

(c) if x=2, then y = |2| + 4 = 6, which is wrong

(d) if x= 2, then y = |2 + 4| = 6, which is wrong

The equality holds for (a).

K= -5

Steps:

Put together like terms

-5k + 2k = 40 - 25

-3k = 40 - 25

-3k = -15

Divide both sides by -3

Then you get your answer.
