Answer:

First two equations

Step-by-step explanation:

9-3x=0

9=3x

3=x

x=3

2x+4=10

2x=6

x=3

9x-1=4

9x=5

x=5/9

3x+1=9

3x=8

x=8/3

x^3+5=6

x^3=1

x=1

5x-7=1

5x=8

x=8/5

In the regular pentagon below, if AP = 4 m and BC = 10 m, find it's area.
12345 [234]

First symmetrically cut the pentagon to get 5 pieces. (So that you will get the idea that this polygon is divided into 5 triangles)

Then find the area of one of the triangles:

Area of Triangle = \frac{1}{2} bh

A = \frac{1}{2} × 4 × 10

A = 20 m²

To find the area of the whole pentagon shape:

A = 20 × 5 = 100 m²

Answer:

942

Step-by-step explanation :

so your d is 300 so your r = 300/2= 150  

a=3.14*r*r= 3.14*150*150= 70650

c= 3.14*d= 3.14*300= 942

OR

The curved surface area of solid cylinder is  

 

As we are given that:

Diameter of solid cylinder = 8 cm

Length or Height o solid cylinder = 140 cm

Formula used to calculate the curved surface area of cylinder is:2n x h

Curved surface area of cylinder =2r x h  

where,

r = radius of cylinder

h = height or length of cylinder

Radius of cylinder =  daimeter

Now putting all the given values in above formula, we get:

Curved surface area of cylinder =  2x 22/7 x 140cm

Curved surface area of cylinder = 3520cm^{2}

Therefore, the curved surface area of solid cylinder is3520cm^{2}
