He radius of a circle is 4.7 inches. find the circumference and area of the circle. use π = 3.14. round to the nearest hundredth.

plz show your work/ you

Step-by-step explanation:

The formula of a circumference of a circle:

r - radius

The formula of an area of a circle:

We have r = 4.7 in.

Substitute:

Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle.

Since the radius of the circle is 4.7 inches, we can plug 4.7 in for the radius in our formula.

Remember that 4.7 in.² is equal to 4.7 inches × 4.7 inches or 22.09 in.².

Now, remember that pi is approximately equal to 22/7 or 3.14. This means that we can estimate the area of the circle by plugging in 3.14 for pi.

Area = 69.36 in.²

Now, let's find the circumference of the circle. To find the circumference of a circle, start with the formula for the circumference.

Circumference = 2πr

Notice that our radius is 4.7 inches which means we can plug in 4.7 inches for the radius in our formula.

Circumference = (2) (π) (4.7 in)

Circumference = 9.4π inches

If 3x + 8x + 4x = 6x + 63, then what is 5x + 23?
