Find the area of a circle with radius r = 6 cm

Mathematics
1 answer:
BlackZzzverrR [31]2 years ago
5 0
The formula to find the area of a circle is pi x radius^2.

pi = 3.14 (in this case)
radius = 6

6^2 (6 x 6) = 36

36 x 3.14 (radius^2 x pi) = 113.04

So, the area of a circle with radius 6 cm is 113.04 cm.

10. The population of India is 1.353 billion, and expected to grow at the rate of one percent
Afina-wow [57]

Answer:

39 years

Step-by-step explanation:

Adapt the formula A = P(1 + r)^n, letting P represent the original population, r the growth rate as a decimal fraction, and n the number of years.

Solve this for n:

2 billion = (1.353 billion)(1 + 0.01)^n

After simplification, we have:

   2

--------- = 1.01^n

1.353

Taking the log of both sides, we get:

log 2 - log 1.353 = n log 1.01, or

log 2 - log 1.353      0.1697

------------------------ = -------------- = 39 years (rounded off from 39.28)

      log 1.01              0.0043

The circumference of circle a is 3 times greater than the circumference of circle
Liono4ka [1.6K]
We know, Circumference of a Circle = 2πr

In mathematical form, You can write it as:
2πr₁ = 3(2πr₂)

2π(12) = 6πr₂

24π = 6πr₂

r₂ = 4 m

In short, Your Answer would be: 4 meter

Hope this helps!

The domain of a quadratic function is all real numbers and the range is y s 2. How many x-intercepts does the
mel-nik [20]

Answer:

There are two x-intercepts.

A quadratic function whose maximum degree two. Therefore, Total two x-intercept possible.

We are given the range of quadratic function y less than equal to 2. It means parabola is downward whose maximum value 2.

Here y is greater than 2 and parabola form downward. Here must be two x-intercept.

If a>0 then form open up parabola.

If a<0 then open down parabola.

Here open down parabola. So, we get total two x-intercept.

Please see the attachment for diagram.
