The circumference of the top rim of the cone-shaped paper cup is 8.66 inches. Find the least amount of paper that can form the c
navik [9.2K]

Answer:

15.59 square inches

Step-by-step explanation:

In the required given diagram, the slant height of the cone was given as 3.6 inches.

The least amount of paper required would be equal to the curved surface area of the cone.

curved surface area of a cone = \pirl

where r is the radius and l the slant height.

circumference of the top rim = 8.66 inches

circumference = 2\pir

⇒ 8.66 = 2\pir

4.33 = \pir

r = 4.33/\pi

curved surface area = \pi x  4.33/\pi x 3.6

                                 = 4.33 x 3.6

                                = 15.588 square inches

Thus, the least amount of paper that can form the cone shaped cup is 15.59 square inches.

What is 9/16 x 12/13 and 7/10 x 5/28
lilavasa [31]

Answer:

1. 9/16 * 12/13 = 27/52

2. 7/10 * 5/28 = 1/8

Step-by-step explanation:

1.

9 / 16 * 12/13

9 * 12 = 108

16 * 13 = 208

108 / 208

Simplify:

27/52


2.

7 / 10 * 5 / 28

7 * 5 = 35

10 * 28 = 280

Simplify:

1/8
