We know that
[area of a circle ]=pi*r²
diameter=4 in
 r=4 in/2-----> 2 in

so
area=pi*2²-----> area of the circle=4*pi in²

the answer is
the area, in square inches, of the circle is <span>3.14 • 2²</span>

Answer:

Option B is correct that is 3.14 . 2²

Step-by-step explanation:

We are given a figure of circle with center O.

From figure.

Length of the diameter of the circle = 4 inches.

⇒ Radius of the circle, r = 4 /2 = 2 inches.

Area of the circle is given by following formula,

Area\:of\:circle=\pi r^2

by putting value of π = 3.14 and radius, r = 2

we get,

Area\:of\:circle=3.14\times2^2

Therefore, Option B is correct that is 3.14 . 2²

attashe74 [19]

Answer:

\frac{4}{9}\ acres

Step-by-step explanation:

step 1

we know that

The area of Tracy's backyard is 1\frac{1}{3}\ acres

Convert to an improper fraction

1\frac{1}{3}=\frac{3*1+1}{3}=\frac{4}{3}\ acres

step 2

To find the area of the garden, multiply the area of the backyard by 1/3

so

\frac{4}{3}(\frac{1}{3})=\frac{4}{9}\ acres

Find the least common denominator for these two rational expressions. B/b^2 -64 -7b/b^2+7b-8
san4es73 [151]

Answer:

The least common denominator is (b-8)(b+8)(b-1)

Step-by-step explanation:

We are given expression as

\frac{b}{b^2-64}-\frac{7b}{b^2+7b-8}

Firstly, we will factor both denominators

b^2-64=b^2-8^2=(b-8)(b+8)

b^2+7b-8=(b+8)(b-1)

so, we can plug it back

\frac{b}{(b-8)(b+8)}-\frac{7b}{(b+8)(b-1)}

First term denominator is

(b-8)(b+8)

Second term denominator is

(b+8)(b-1)

So,

Least common denominator will be

(b-8)(b+8)(b-1)

So, we get

LCD=(x-8)(x+8)(x-1)

1) What is the solution to x - 5 = 27?
Phoenix [80]
X - 5 = 27

Isolate the x, add 5 to both sides (because of equal sign)

x - 5 = 27
x - 5 (+5) = 27 (+5)
x = 27 + 5
x = 32

x = 32 is your answer

hope this helps
