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

name the intersection of rs and st assume that rs and st are not collinear. a. rs. b.ts c. t d.s

Katen [24]

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

RS and ST intersect to each other but they are not collinear.

Since we can see that 'S' is common in both RS and ST,

as RS and ST have common vertex i.e. "S".

So, The intersection of RS and ST is 'S'.

So, Option 'd' is correct.

A=1/2h(a+b) <br> what is h

Ilya [14]

Answer:

$h = \frac{2 A}{(a + b)}$

Step-by-step explanation:

$A = \frac{1}{2} h(a + b) \\ \\2 A = h(a + b) \\ \\ \frac{2 A}{(a + b)} = h \\ \\ \huge \red{ \boxed{h = \frac{2 A}{(a + b)} }}$
