Answer: Area of the circle will be

50.288

Step-by-step explanation:

Area of a circle is calculated by A=πr^2

Where r is the radius, given as 4

π is a mathematical constant of 3.143

Slot the values into the formula:

A = 3.143 x 4^2

A = 3.143 x 16

A = 50.288

Anna hiked 95⁄8 miles in 23⁄4 hours. How fast did she walk overall? A. 31⁄4 miles per hour B. 35⁄8 miles per hour C. 31⁄2 miles
Pani-rosa [81]

Answer:

C. 3 1/2 miles per hour

Step-by-step explanation:

I just converted the fractions to decimal form.

5/8 = 0.625           9 + 0.625   = 9.625

3/4 = 0.75             2 + 0.75     = 2.75

Now divide the 2 numbers:

9.625 / 2.75 = 3.5

Finally, convert the decimal back to a fraction:

3.5 = 3 1/2

Hope this helps!

Hi, can you help me to find (if passible) the complement andsupplement of the angle 3pi/ 4.
nika2105 [10]

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.

In radians this are

\begin{gathered} \frac{\pi}{2}\text{ for }90\degree \\ \pi\text{ for }180\degree \end{gathered}

To find the complement of 3π/4, subtract it by π/2

\frac{\pi}{2}-\frac{3\pi}{4}=-\frac{\pi}{4}

To find the supplement of 3π/4, subtract it by π.
