Step-by-step explanation:
formula for cylinder:V=πr2h
shape of the base: circle
formula for circle: A=πr2
radius: 6.5cm
height: 16cm
V=3.14x6.5^2x16
2122.64cm^3
Answer:
Combine points A with C and A with B. Consider ΔABD and ΔACD:
1. AD is common side, then AD\cong AD;
2. CD\cong BD - given in the diagram;
3. \angle ADB\cong \angle ADC .
By SAS Postulate, \triangle ABD\cong \triangle ACD . Congruent triangles have congruent corresponding sides and congruent corresponding angles, so AC\cong AB .
From this proof you can see that correct choice is option D (In triangles ABD and ACD, two sides and an included angle are equal.)
Step-by-step explanation:
Yes it describes only a parameter because <span>a numerical characteristic of a population, as distinct from a statistic of a sample was use. only 35 out of the 1200 accountants salary was used in calculating an average salary. it will be real if use all the number of accountant in calculating the average salary</span>
Answer: 4,772.8 cm2
Step-by-step explanation:
Hi, to answer this question we have to calculate measures of the rectangular label:
The width of the label is equal to the height of the can (8 cm), and the length is equal to the perimeter of the top or bottom of the can.
Perimeter of a circle (circumference): 2 π radius
Replacing with the values given:
C = 2 (3.14) 5 = 31.4 cm
So, the area of one label is:
Area of a rectangle: length x width = 31.4 x 8 = 251.2 cm2
Multiplying for the number of labels (19)
251.2 x 19 = 4,772.8 cm2
