Answer:

Step-by-step explanation:

Area is pi times r squared. I don't know how to write that on the keyboard. Take your pi(3.142) times the radius(6.2)squared. Pemdas tell us to do exponents first, so 6.2 squared is 38.44. To square a number, just multiply it times itself. So now, we have pi(3.142) times the squared radius(38.44). So, 3.142X38.44=

120.778 Second place is seven followed by eight. Round up. 120.78

Nina [5.8K]

Pearson mode skewness, also called Pearson's first coefficient of skewness, is a way to figure out the skewness of a distribution. The mean, mode and median can be used to figure out if you have a positively or negatively skewed distribution. If the mean is greater than the mode, the distribution is positively skewed.
