Answer 2
Answer: Circumference of a circle = 2 \pi r

They are all multiplied by each other
r = radius 
we know our radius is 40 
and... \pi = 3.14 

so we would use this expression 
3.14 x 40 x 2 

As a added bonus ill solve it for you :P
3.14 x 40 x 2 = 251.2 
The circumference of this ice skating rink is 251.2 feet

Julia's great dane weighs 45 kgand Jake's chihuahua weighs 15 kg. How much bigger, as a percentage, is julia's dog?

Answers

Answer : The percentage will be, 200%

Step-by-step explanation :

First we have to calculate the excess weight.

Excess weight = 45 kg - 15 kg

Excess weight = 30 kg

Now we have to calculate the percentage of excess weight.

Percentage of excess weight = \frac{\text{Excess weight}}{\text{Weight of Jake's}}* 100

Percentage of excess weight = (30kg)/(15kg)* 100

Percentage of excess weight = 200 %

Therefore, the percentage will be, 200%
45kg-15kg=30kg Percentage: 30kg=0.3% Percentage =0.3%
