Given: 

Circle with radius 5cm and 3 cm

To Find: 

How much bigger is the area of a circle.

Solution:

Area of circle with Radius 5cm

Area of circle = πr²

Area of circle = 22/7 × 5 × 5

Area of circle = 22/7 × 25

Area of circle = 78.54 cm²

Now,

Area of circle with Radius 3 cm

Area of circle = 22/7 × 3 × 3

Area of circle = 22/7 × 9

Area of circle = 28.27 cm²

= 78.54 - 28.27

= 50.27cm

Hence,

Area of circle is 50.27cm more than that area of circle with radius 3cm

Which is a closer estimate of pi? Explain your answer.

nydimaria [60]

The fraction 22/7 has a value of 3.142857, so it has the same first three digits as pi. Both 3.14 and 22/7 are approximations of pi. In fact, 22/7 is close to pi than 3.14 is. Pi is irrational. That is, the decimal expansion never ends and never repeats, so any number of decimal places we wrote out is an approximation. The approximation 3.14 is about 1/2 percent off from the true value, and the fairly well know 3.141559 is within 0.000084 percent.

You are comparing to wireless services. Verizon changes $35 a month and $5 per gigabyte of data.

ikadub [295]

A) Gigabytes = x
B) 35+5x = 25+10x
10 = 5x
2 = x
C) After 2 gigabytes, the wireless services will cost the same ($45)

Zaheer, a boy of height 1.5m was watching the entire programme. Initially he observed the top of theflagpoleat an angle of eleva

torisob [31]

Answer:

$h = 15.163\ meters$

Step-by-step explanation:

(Assuming the correct angles are 30° and 45°)

We can use the tangent relation of the angle of elevation to find two equations, then we can use these equations to find the height of the pole.

Let's call the initial distance of the boy to the pole 'x'.

Then, with an angle of elevation of 30°, the opposite side to this angle is the height of the pole (let's call this 'h') minus the height of the boy, and the adjacent side to the angle is the distance x:

$tan(30) = (h - 1.5) / x$

Then, with an angle of elevation of 45°, the opposite side to this angle is still the height of the pole minus the height of the boy, and the adjacent side to the angle is the distance x minus 10:

$tan(45) = (h - 1.5) / (x - 10)$
