I agree with the other person ^^^
The answer is 286
Step-by-step explanation:
70 x 4 = 280 plus 6 equals 286
18 because, 3 in the first round, 6 in the second round, 9 in the third round, 12 in the fourth round, 15 in the fifth round, and 18 on the sixth round.
Hope this helps you :)
Answer:
The distance of the dot above the ground is 28.9 in
Step-by-step explanation:
see the attached figure with letters to better understand the problem
we know that
The triangle ABC is an isosceles triangle
CA=CB=15 in ------> is the radius of the circle
∠ACD+112°=180° ---> because the diameter divide the circle into two equal parts
∠ACD=180° -112°=68°
In the right triangle ACD
Find AD we have sin(68°)=AD/AC AD=AC*sin(68°) substitute the value AD=15*sin(68°)=13.9 in
Find the distance AB
AB=2*AD AB=2*13.9=27.8 in
The diameter is equal to
2*15=30 in
The distance of the dot above the ground is equal to
AB+(30-27.8)/2
27.8+1.1=28.9 in
