Answer:
Step-by-step explanation:
d = 17 cm
r = 17/2 = 8.5 cm
Circumference of circle = πd
= 3.14 * 17
= 53.38 cm
Area of circle = πr²
= 3.14 * 8.5 * 8.5
= 226.865 cm²
Uhm i’m not the best at this but i’ll give it a try . they would probably have to have one same number you should try pemdas maybe idk :( sowwy
Answer:
<h3>"When constructing a confidence interval for a population mean, if a population is normally distributed and a small sample is taken, then the distribution of is based on the <u> "t" </u>distribution</h3>
Step-by-step explanation:
Given that "When constructing a confidence interval for a population mean, if a population is normally distributed and a small sample is taken, then the distribution of is based on the "<u>t"</u>distribution."
Because the given sample size is smaller so we have to use the "t" distribution for constructing the confidence interval for a given population
Find all the areas and add them together
Base Rectangle : LxW = 14 x 12 = 168
Bases Triangles (2) 2x (8x12)/2 = 96
2 Lateral rectangles 14x10 =140 (double) = 280
Surface Area = 168 +96 + 280 = 544
