Question

Use the formula given to solve all those 3 please ASAP!!!

Answer 1

Below!

Explanation:

We know that:

• Volume of cylinder: πr²h
• Volume of cone: 1/3πr²h

________________________________________________

Solution (Surface area of rectangular prism):

• 2(2 x 4) + 2(4 x 4) + 2(2 x 4)
• => 2(8) + 2(16) + 2(8)
• => 16 + 32 + 16
• => 64 yd²

________________________________________________

Solution (Volume of cylinder):

• πr²h
• => 22/7 x 11² x 10
• => 22/7 x 121 x 10
• => 22/7 x 1210
• => 26620/7 mm³

________________________________________________

Solution (Volume of cone):

• 1/3πr²h
• => 1/3 x 22/7 x r² x h
• => 1/3 x 22/7 x 3² x 6
• => 22/7 x 3 x 6
• => 22/7 x 18
• => 396/7 ft³

Answer 2

1) 64 yd² 2) 3801.3 mm³ 3) 56.55 ft³

Explanation:

Surface area of rectangular prism: Area =2(wl+hl+hw)

= 2(4*2+4*2+4*4)

= 64 yd²

Volume of cylinder = πr²h

= π*11²*10

= 1210π or 3801.3 mm³

Volume of cone =
`(1)/(3) \pi r^(2)h`

= 1/3 *π*3²*6

= 18π or 56.55 ft³
