I am assuming the both cylinders have the same measure of radius. They only differ in height.

Larger Cylinder = 343 ft³
Smaller Cylinder = 125 ft³ ; height = 5 ft.

We can use proportion for this problem; a:b = c:d where ad = bc

5 ft :125 ft³ = x : 343ft³
5 ft * 343 ft³ = 125 ft³ * x
1715 ft⁴ = 125 ft³ * x
1715 ft⁴ ÷ 125 ft³ = x
13.72 ft = x  height of the larger cylinder.

Cone S = 768pi cm³
Cone T = 6144pi cm³ ; height = 24 cm

24 cm : 6144 cm³ = x : 768 cm³
24 cm * 768 cm³ = 6144 cm³ * x
18,432 cm⁴ = 6144 cm³ * x 
18,432 cm⁴ ÷ 6,144 cm³ = x
3 cm = x height of Cone S.

The Total Surface Area for the shape below is _________. (round to nearest tenth.)
gavmur [86]

Answer:

=193.2 cm

Step-by-step explanation:

  • Figure out the triangles first
  • Area= Base times Height divided by 2
  • first figure out one triangle A= (6)(5.2)/2 = 15.6 (brackets means times and the slash means divide
  • times it by 2 so you get the area of both triangles (15.6)(2)= 31.2
  • Now figure out the rectangles
  • Area= Base times Height
  • A=(6)(9) = 54
  • Then times it by 3 to get the area of all three triangles
  • (54)(3)= 162
  • Now add 162 and 31.2 and you get 193.2 cm

Find the Volume (look at the picture)
xeze [42]

Answer:

V ≈ 263.9 units³

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = \frac{1}{3} πr²h ( r is the radius and h the height )

Here r = 6 and h = 7 , then

V = \frac{1}{3} π × 6² × 7

   = \frac{1}{3}π × 36 × 7

   = \frac{1}{3}π × 252

   = 84 π

   ≈ 263.9 units³ ( to 1 dec. place )
