Today is the birthday of Rahul and he is 3 times

Marat540 [252]

Answer:

b. 36 years

Step-by-step explanation:

Today

Nirmala = x years

Rahul = 3x years

In 13 years

Nirmala = 3x + 13 years

Rahul = 2(x+13) - 1

3x + 13 = 2(x+13) - 1

3x + 13 = 2x + 26 - 1

3x + 13 = 2x + 25

3x - 2x = 25 - 13

x = 12

Nirmala = x years

= 12 years

Rahul = 3x years

= 3(12)

= 36 years

The age of Rahul today is 36 years

Two cylinders are shown below. Find the volume of each cylinder. Use 3.14 for pie. Enter your answers rounded to the nearest hun

Alchen [17]

Given:

For cylinder P: radius = 4.25 in. and height = 14 in.

For cylinder Q: radius = 7 in. and height = 8.5 in.

To find:

The volume of each cylinder.

Solution:

Volume of a cylinder is

$V=\pi r^2h$

where, r is radius and h is height. Use 3.14 for $\pi$ .

Using the above formula, the volume of cylinder P is

$V_P=(3.14)(4.25)^2(14)$

$V_P=794.0275$

$V_P\approx 794.03$

Using the above formula, the volume of cylinder Q is

$V_Q=(3.14)(7)^2(8.5)$

$V_Q=1307.81$

Therefore, the volume of cylinder P is 794.03 sq. in. and volume of cylinder Q is 1307 sq. in.
