The formula for volume of a cylinder is V= PI x r^2 x H
r = radius = 1/2 diameter = 1/2*1.8 = 0.9 meters
Height = 25
Volume = PI x 0.9^2 x 25
= PI x 0.81 x 25
= PI x 20.25
= 63.62 cubic meters
Answer:
(4 × 3) + (1 × 1)
Step-by-step explanation:
Sum means adding, so you are adding the product of 4 and 3 to the product of 1 and 1.
Product means multiplying, so you are multiplying 4 and 3 together, and since you just want an expression, this is expressed as 4 × 3.
You are also multiplying 1 and 1 together, so that can be expressed by 1 × 1.
Since you are adding these together, you just put a plus sign in between the two terms. That gives you (4 × 3) + (1 × 1).
Answer:
The area under the normal curve from the mean to 118.8. is 0.47
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
Find the area under the normal curve from the mean to 118.8.
This is the pvalue of Z when X = 118.8 subtracted by the pvalue of Z when X = 100.
X = 118.8
has a pvalue of 0.97
X = 100
has a pvalue of 0.5
0.97 - 0.5 = 0.47
The area under the normal curve from the mean to 118.8. is 0.47
Answer:
21
Step-by-step explanation:
7 units to the left of 28 on the number line is the number 21.
Option D is correct. The required compatible number is 480 ÷ 60 = 8
Compatible numbers are numbers that have a close approximate to a given value
Given the expression 488 ÷ 62
The compatible number for 488 is 480
The compatible number for 62 is 60
Using these compatible numbers to solve the expression will give:
488 ÷ 62
= 480 ÷ 60
= 480/60
= 48/6
= 8
Hence the correct option will be 480 ÷ 60 = 8
