There’s only one question (picture)

Area of circle is 314 inches^2

Circumference of circle is 62.8 inches

Step-by-step explanation:

We need to find area and circumference of the circle whose diameter is 20 inches.

Area of circle

The formula used to find area of circle is:

$Area=\pi r^2$

value of π = 3.14

we know radius = diameter/2

So, radius = 20/2 = 2

Putting value of π and radius we get Area:

$Area=\pi r^2\\Area= 3.14*(10)^2\\Area=3.14*100\\Area=314\,\,inches^2$

So, Area of circle is 314 inches^2

Circumference of Circle

The formula used to find circumference of circle is:

$Circumference=\pi d$

value of π = 3.14

diameter= 20

Putting value of π and diameter we get Circumference:

$Circumference=\pi d\\Circumference=3.14*20\\Circumference=62.8\,\,inches$

So, circumference of circle is 62.8 inches
