Answer:
b
Step-by-step explanation:
r=d/2=11.4/2=5.7
slant surface area=2πr*h=11.4×3.14×4.4=157.5024 cm^2
area of base and top=2(πr²)=2×3.14×(5.7)²=204.0372 cm²
total surface area=157.5024+204.0372=361.5396=361.5 sq. cm
Answer:
180
Step-by-step explanation:
Base x Height
So 9 x 20 to get 180
Answer:
the second one I can't give a explanation cause my wrist is broken so it's harder to type hope this helps
203---- 100%
x-----148%
x=203*148/100=203*1.48=300.44
Answer:
Pa - Pb
Step-by-step explanation:
The mean of the distribution of sample differences will always be the difference between the population proportion, That is ; Pa - Pb ; This is because according to the central limit theorem which says the sampling distribution of sample means approaches a normal distribution as sample size gets larger irrespective if the shape of the Population distribution. Hence, the distribution of sample differences will follow a normal distribution and the mean will Hence be the difference in the population mean.
