Answer:

P = 6x + 10

Step-by-step explanation:

Perimeter of a rectangle

= 2(L + W)

Where L = length

W = width

Given

L= (x + 6)

W =(2x - 1)

Perimeter = 2( x+6 + 2x -1)

Simplify the bracket first

P = 2(x + 2x +6 - 1)

P = 2(3x + 5)

Now , expand the bracket

P = 2 x 3x + 2 x 5

P = 6x + 10

Answer:

6x +10

Step-by-step explanation:

Perimeter = 2*(length + width)

= 2* (x+6 + 2x-1)

=2*(3x +5)

=2*3x + 2*5

=6x + 10

the diameter of a cylinder is 14cm.the height of the cylinder is 9cm. calculate the Volume and curved surface area

kicyunya [14]

Answer:

The volume is 1386 cm³ and curved surface area is 396 cm².

Step-by-step explanation:

Given that,

The diameter of a cylinder is 14 cm

Height of the cylinder is 9 cm

We need to find the volume and curved surface area .

If r is the radius, r = 14/2 = 7 cm

Volume of a cylinder is given by :

$V=\pi r^2 h\\\\V=\dfrac{22}{7}\times (7)^2 \times 9\\\\V=1386\ \text{cm}^3$

The curved surface area of the cylinder is given by :

$A=2\pi r h\\\\A=2\times \dfrac{22}{7}\times 7\times 9\\\\A=396\ \text{cm}^2$

So, the volume is 1386 cm³ and curved surface area is 396 cm².
