Question:
Find the surface area of the following figure below. Use 3.14 for pi
Answer:
9
Step-by-step explanation:
The circle has the same value of the side which is 3 so the length and width is 3 too. So the formal is L x W = Area. So this means 3 x 3 = 9
This is a simple one just multiply the sides by the same number
14/32, 28/48
The area of the shaded region is 0.1271 (12.71%).
<h3>What is the
z score?</h3>
Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (raw score - mean)/standard deviation
Given:
Mean 0 and standard deviation 1. Hence, for z=-1.14:
P(z < -1.14) = 0.1271
The area of the shaded region is 0.1271 (12.71%).
