Hello!
To find the volume of a cone, use the formula: V = 1/3πr²h.
In the photo, the height is 6 units, and the diameter is 8 units. Since the radius is half the diameter, then the radius is 4 units.
V = 1/3π(4)²(6)
V = 1/3(6)(16)π
V = 2(16)π
V = 32π
V = 100.5309... This can be rounded to about 100.5.
Therefore, the volume of this cone, is about 100.5 units³.
Answer: 20
Step-by-step explanation:
50 over 1 times 2 over 5 which equals 100 over 5. Divide both numbers by 5 which equals 20.
Step-by-step explanation:
Here is the answer to this question,
His hypothesis would be:
Null hypothesis:
H0: μ(new) - μ(regular) = 0
Alternate hypothesis:
H1: μ(new) - μ(regular) > 0
The consumer is testing to know if his new detergent is better off in cleaning than the regular. The question says that higher scores after cleaning is used to signify which is better based on sufficiently clean garment. Since he is interested in knowing the mean scores of the differences, he should use the hypothesis I stated above.
Answer:
97.5 miles
Step-by-step explanation:
d = 65t
where d is the distance in miles and t is the time in hours
Therefore, to calculate how many miles the car travels in 1.5 hours, substitute t = 1.5 into the equation:
d = 65 x 1.5 = 97.5 miles
Answer:
A. 90
Step-by-step explanation:
Rotating an angle does not change its measure. ABC is 90 degrees as marked by the corner symbol. After rotating, the angle stays 90 degrees.
