Suppose the area of a circle is 254.4696 square inches. Whats the radius of the circle (use pie=3.1416. A. 18 in. B. 81 in. C. 9

zalisa [80]

Answer:

The radius of the circle is 9 in

Choice C is correct

Step-by-step explanation:

254.4696 square inches. Whats the radius of the circle (use pie=3.1416.

The area of a circle with radius r is given as;

$A=\pi *r^{2}$

We substitute the given area and the value of pi given to solve for the radius;

$254.4696=3.1416*r^{2}\\\\r^{2}=\frac{254.4696}{3.1416}\\\\r^{2}=81\\\\r=\sqrt{81}=9\\\\r=9$

It is known that the function f(x)=3(1.5) ^x has an area of 48.787 units^2"over the interval 0 <=x<=5.If g(x)=f(x)-3, what

ch4aika [34]

We have

$\displaystyle \int_0^5 g(x)\; dx = \int_0^5 (f(x)-3)\; dx = \int_0^5 f(x)\; dx - \int_0^5 3\; dx$

The first integral is known and it is 48.787. The second integral is the area of a rectangle:

$\int_0^5 f(x)\; dx - \int_0^5 3\; dx = 48.787 - 15 = 33.787$

Dennis_Churaev [7]

Answer:

x = 11

Step-by-step explanation:

Take the fifth root on both sides.

27(x-2) = 3^5

27x-54 = 3^5

27x = 243 + 54

27x = 297

x = 297/27

x = 11
