Answer: 28.89 \text{ inches}

Step-by-step explanation:

We know that formula to calculate the circumference of a circle is given by :-

\text{Circumference}=2\pi r, where r is the radius of the circle.

Given: The radius of the circle : d=\ 4.6\text{ inches}

Then , the circumference of a circle is given by :-

\text{Circumference}=2(3.14) (4.6)\approx28.89 \text{ inches}

Hence, the  approximate circumference of a circle with diameter equal to 8 ft = 28.89 \text{ inches}

8.1 = 0.9a, how do you solve?
GrogVix [38]

Answer:

a = 9

Step-by-step explanation:

Simplifying

8.1 = 0.9a

Solving

8.1 = 0.9a

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-0.9a' to each side of the equation.

8.1 + -0.9a = 0.9a + -0.9a

Combine like terms: 0.9a + -0.9a = 0.0

8.1 + -0.9a = 0.0

Add '-8.1' to each side of the equation.

8.1 + -8.1 + -0.9a = 0.0 + -8.1

Combine like terms: 8.1 + -8.1 = 0.0

0.0 + -0.9a = 0.0 + -8.1

-0.9a = 0.0 + -8.1

Combine like terms: 0.0 + -8.1 = -8.1

-0.9a = -8.1

Divide each side by '-0.9'.

a = 9

Simplifying

a = 9
