Answer:

Diameter of the can = 18 Cm

Step-by-step explanation:

Given:

Curved surface of cylindrical can = 162\pi

Height of cylindrical can = 9 Cm

Find:

Diameter of the can = ?

Computation:

Curved surface of cylindrical can = 2\pirh

162\pi  = 2\pi rh\\\\\frac{162\pi }{2\pi }=  r\times 9\\\\81 =  r\times 9\\\\\frac{81}{9}=r

r=9 Cm

Diameter of the can = 2×r

Diameter of the can = 2×9 Cm

Diameter of the can = 18 Cm

Solve the equation. \dfrac32 + b = \dfrac74 2 3 ​ +b= 4 7 ​ start fraction, 3, divided by, 2, end fraction, plus, b, equals, sta
Xelga [282]

Given:

The equation is

\dfrac{3}{2}+b=\dfrac{7}{4}

To find:

The value of b.

Solution:

We have,

\dfrac{3}{2}+b=\dfrac{7}{4}

Subtracting both sides by \dfrac{3}{2}, we get

b=\dfrac{7}{4}-\dfrac{3}{2}

b=\dfrac{7-2(3)}{4}

b=\dfrac{7-6}{4}

b=\dfrac{1}{4}

Therefore, the value of b is \dfrac{1}{4}.

What is the numerical coefficient of the a^8*b^2 term in the expansion of ((1/3)a^2 - 3b)^6 ?
zhuklara [117]

In the binomial development, the main problem is calculation of binomial coefficients.

If we want to get term a∧8*b∧2 we see that this is the third member in binomial development (n 2) a∧n-2*b∧2

The given binomial  is ((1/3)a∧2 - 3b)∧6, the first element is (1/3)a∧2, the second element is (-3b) and n=6 when we replace this in the formula we get

(6 2) * ((1/3)a∧2)∧(6-2) * (-3b)2 = (6*5)/2 * ((1/3)a∧2)∧4 *9b∧2= 15*(1/81)*9 *(a∧8b∧2) =

= 15*9* a∧8b∧2 = 135*a∧8b∧2

We finally get numerical coefficient 135

Good luck!!!
