35 points and 35 points on same repeat question on my drop-list questions.
Find the area? so you can just leave answer only in each. But show workings here please.

Volume = 336,78 ft³

Surface Area = 367,04 ft²

Note :

l = long

w = wide

h = height

d = diameter

r = radius

V = Volume

SA = Surface Area

Known :

Rectangular prism :

l = 7 ft

w = 4 ft

h = 9 ft

Cylinder :

d = 6 ft

r = ½ d = ½ × 6 = 3 ft

h = 3 ft

Asked :

• V = ...?

• SA = ...?

Answer :

V = V rectangular prism + V cylinder

= (l × w × h) + (πr²t)

= (7 × 4 × 9) + (3,14 × 3² × 3)

= 252 + 84,78

= 336,78 ft³

SA = SA rectangular prism + SA cylinder

= (2 (lw + lh + wh)) + (2πr (r + h))

= (2 (7×4 + 7×9 + 4×9)) + (2 × 3,14 × 3 (3 + 3))

= (2 (28 + 63 + 36)) + (18,84 × 6)

= (2 × 127) + 113,04

= 254 + 113,04

= 367,04 ft²

Area = 310.52 ft²

Step-by-step explanation:

Cuboid - circle + curved surface of the cylinder + circle

= surface area if cuboid + curved surface cylinder

2[(9×7) + (9×4) + (7×4)] + 2pi×(6/2)×3

254 + 18pi

254 + 18(3.14)

310.52 ft²

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

can you put the picture up?
