Remember P.E.M.D.A.S to be able to solve the equations. We'll be using the E (exponents) and M (Multipliction)

SOLVING...

1. 2.5 x 10^4

Solve Exponent... 10^4 = 10000

Multiply... 2.5 x 10000 = 25000

2. 3.4 x 10^4

Solve Exponent... 10^4 = 10000

Multiply... 3.4 x 10000 = 34000

25000 and 34000 are your answers

The diameter of a quarter is 2.5 cm. What is it’s circumference?

anastassius [24]

Answer:

7.85 cm

Step-by-step explanation:

The circumference of a circle can be found using the following formula.

$c=\pi d$

The diameter is 2.5 centimeters. Therefore, we can substitute 2.5 cm in for d.

$c=\pi *2.5 cm$

Now, find the circumference.

- In terms of pi:

$c=\pi *2.5 cm$

$c= (2.5)\pi cm$

$c= 2.5\pi cm$

-Using 3.14 as pi

$c=\pi *2.5 cm$

$c=3.14 *2.5 cm$

$c=7.85 cm$

-Using 3.14159... as pi

$c=\pi *2.5 cm$

$c=7.85398163 cm$
