Find the surface area of the composite figure. need help asap. Thank You

A=276.52 cm²

Step-by-step explanation:

To find the surface area of the figure, we can find the surface area of the rectangular prism and hemisphere. Then we would add them together.

Rectangular Prism

A=2(lw+hl+hw)

Since we are given the length, width, and height, we can directly plug them into the equation and solve.

The surface area for the rectangular prism is 220 cm².

----------------------------------------------------------------------------------------------------------------

Hemisphere

A=2πr²

This formula above is derived from the formula for surface area of a sphere.

The surface area of a sphere is A=4πr². Since the picture displays half of a sphere, we divide that by 2. This gives us A=2πr².

Since we have the radius, all we have to do is plug it in.

                            *Note I used 3.14 instead of π.

----------------------------------------------------------------------------------------------------------------

Now that we have the surface area of the hemisphere and rectangular prism, we add them together to find the surface area of the entire prism.

A=220+56.52=276.52 cm²

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
