Answer:

$\pi$ or 3.14

Step-by-step explanation:

The formula for the area of a circle is $\pi r^2$

If this quarter circle were to be a full circle, the area would be $4\pi$

Since this is a quarter circle as the angle is 90 degrees (which is a quarter of 360), the area of this shape is $\pi$ .

Answer:

A = pi

= 3.14

Step-by-step explanation:

We have 1/4 of a circle

The area of a circle is given by pi r^2

The area of this quarter circle is

A = 1/4 pi r^2

The radius is 2

A = 1/4 pi (2)^2

A = 1/4 pi (4)

A = pi

We can use 3.14 for pi

A = 3.14

An equation is shown below: 1 over 2 multiplied by x plus 3 over 2 equals 2 to the power of x What is the solution to the equati

Alborosie

Answer:

First option is correct. The solution of the equation is x=1.

Step-by-step explanation:

The given equation is

$\frac{1}{2}x+\frac{3}{2}=2^x$

The value of x, which satisfy the above equation is the solution of the given equation.

Put x=1 in the given equation.

$\frac{1}{2}(1)+\frac{3}{2}=2^{1}$

$\frac{1+3}{2}=2$

$\frac{4}{2}=2$

$2=2$

Since left hand side is equal to right side, therefore first option is correct.

Put x=2 in the given equation.

$\frac{1}{2}(2)+\frac{3}{2}=2^{2}$

$\frac{2+3}{2}=4$

$\frac{5}{2}=4$

Since left hand side is not equal to right side, therefore second option is correct.

Put x=4 in the given equation.

$\frac{1}{2}(4)+\frac{3}{2}=2^{4}$

$\frac{4+3}{2}=16$

$\frac{7}{2}=16$

Since left hand side is not equal to right side, therefore third option is correct.

Put x=8 in the given equation.

$\frac{1}{2}(8)+\frac{3}{2}=2^{8}$

$\frac{8+3}{2}=256$

$\frac{11}{2}=256$

Since left hand side is not equal to right side, therefore fourth option is correct.
