Answer:
diameter = 18.8 ft
circumference = 56.1 ft
Step-by-step explanation:
diameter = 2 x radius = 2 x 9.4 = 18.8 ft
circumference = 2r = 2(9.4) = 56.061 rounded to the nearest tenth is 56.1
So to find h, you need to isolate that variable onto one side.
To do this, divide both sides by πr², and <u>your answer will be , or the 2nd option.</u>
Answer:
1m 54cm
Step-by-step explanation:
10 students at 1m 40cm
15 students at 1m 58cm
13 students at 1m 60cm
Keep in mind that ratio between cm to m is 1cm/0.01m.
So let find the average by converting cm to m first for the 38 students.
10 students: 1m + (40cm)(0.01m/1cm) => 1.4 m
15 students: 1m + 58cm(0.01m/1cm) => 1.58 m
13 students: 1m 60cm(0.01m/1cm) => 1.60 m
so the average is weighted:
(10*1.4 +15*1.58 + 13(1.6))/38
Therefore the average model height is 1.54 m or 1m 54cm
