Step-by-step explanation:

It is given that, Steve is making a circular shield with a radius of 11 inches for a school play. We need to find the length of cardboard he need to make the outer border of the shield. It means that we need to find the circumference of the circular shield of radius 11 inches.

So,

C=2\pi r\\\\C=2\times 3.14\times 11\\\\C=69.08\ \text{inches}

So, he will need 69.08 inches of cardboard to make the outer border of the shield.

you need to find surface are and the formula is : a=2(wl+hl+hw)

with the numbers plugged in the equation is: 2(9x16+4x16+4x9)

now to multiply:2(144+64+36)

now to apply distributive property: 2x144 + 2x64 + 2x36

                                                         288 + 128 + 72

                                                          416 + 72

2 1/7 pieces

Step-by-step explanation:

A factory makes rectangular sheets of cardboard, each with an area 2 1/2 square feet. Each sheet of cardboard can be cut into smaller pieces of cardboard measuring 1 1/6 square feet. How many smaller pieces of cardboard does each sheet of cardboard provide?

Each sheet of cardboard = 2 1/2 square feet

Each smaller pieces of cardboard = 1 1/6 square feet

Number of smaller pieces of cardboard per sheet of cardboard = Each sheet of cardboard ÷

Each smaller pieces of cardboard

= 2 1/2 square feet ÷ 1 1/6 square feet

= 5/2 ÷ 7/6

= 5/2 × 6/7

= (5*6) / (2*7)

= 30/14

= 15/7

= 2 1/7 pieces

Number of smaller pieces of cardboard per sheet of cardboard = 2 1/7 pieces

439.5 in.^2

Step-by-step explanation:

The lateral area of a cone is given by the formula

A=\pi r h'

where

A is the lateral area

r is the radius of the cone

h' is the slant height of the cone

Here for the cone shaped party hats we have:

r = 7 in. is the radius of each cone

h' = 4 in. is the slant height

So the lateral area of each conic hat is

A=\pi (7)(4)=87.9 in.^2

However, here we have five hats in total; therefore, the total lateral area of the 5 hats is

A'=5A=5(87.9)=439.5 in.^2

So, the amount of cardboard that Robert needs to make the 5 conic hats is 439.5 in.^2.
