Select the choice that translates the following verbal phrase correctly to algebra: y less than 21

8_murik_8 [283]

Y less than 21 = 21 - y

Remember, "less than" indicates a subtraction with the terms in inverted order.

Hope I helped!

A circular plate has circumference 21.4 inches. What is the area of this plate? Use 3.14 for pi.

Brut [27]

Answer:

The area of this plate is $36.31\ \text{inches}^2$ .

Step-by-step explanation:

We have,

Circumference of a circular plate, C = 21.4 inches

The circumference of a circular shape is given by :

$C=2\pi r$

r is radius of circular shape

$r=\dfrac{C}{2\pi}\\\\r=\dfrac{21.4}{2\times 3.14}\\\\r=3.4\ \text{inches}$

Area of this plate is given by :

$A=\pi r^2\\\\A=\pi (3.4)^2\\\\A=36.31\ \text{inches}^2$

So, the area of this plate is $36.31\ \text{inches}^2$ .
