Volume of the cone: 1/3 of area of the circle * the height
(1/3)π5²*5=(125/3)π
volume of the cylinder: area of the circle *the height: π5²*10=250π
add up: (125/3)π+(125/3)π+250π≈1047.2
D is the correct answer

The volume of a rectangular prism is 2,058cm. The Length of the prism is 3 times the width. The height is twice the width. Find

Nat2105 [25]

v = l x w x h

v = 2058

width = x

height = 2x

length = 3x

2058 = 3x*2x*x =

2058 = 6x^3=

343 = x^3

x = 7

2*7 = 14

3*7 = 21

21*14*7 = 2058

height is 14 cm

A shark is 80 feet below the surface of the water. It swims up and jumps out of the water to a height of 15 feet above the surfa

lyudmila [28]

Answer:

∆y = 95 ft

the vertical distance the shark travels is 95 ft

Step-by-step explanation:

Given;

Initial position y1= 80 ft below the surface of water = -80ft

Final Position y2 = 15 ft above the surface = +15ft

The vertical distance travelled by the shark is;

∆y = y2 - y1 = 15 - (-80) ft

∆y = 15 +80 ft

∆y = 95 ft

the vertical distance the shark travels is 95 ft

What are the values of x and y for which quadrilateral is ABCD is a parallelogram? Explain.

Mrac [35]

Answer:

The value of x = 2.

The value of y = 1.

Step-by-step explanation:

The length of opposite sides of a parallelogram are equal.

Hence, the length of 4x - 3 and x + 3 are equal.

Similarly, the lengths of 3y and 5y - 2 are equal.

$\therefore 4x - 3 = x + 3$

$\implies 3x = 6$

$\implies \textbf{x = 2}$

And $3y = 5y - 2$

$2y = 2$

$\implies \textbf{y = 1}$

Therefore, the values of x and y are: 2; 1 respectively.
