Answer:61.8°
Step-by-step explanation:
Length of arc=(theta)/360 x 2 x π x radius
9.7=(theta)/360 x 2 x 3.14 x 9
9.7=56.52(theta)/360
cross multiply
9.7 x 360=56.52(theta)
3492=56.52(theta)
Divide both sides by 56.52
3492/56.52=56.52(theta)/56.52
61.8=theta
theta=61.8°
$112
1-1/5=4/5
4/5 x 140 =112
hope this helps :)
Volume should be 226.08
volume of a cone= 1/3 pi radius squared multiplied by height
6x6=36 multiply by height 36x6=216 divide by 3=72 now multiply by pi =226.08
your answer is 226.08
Answer: 9 7/12
TO simplify the answer make common denominator which would be 12 so 5/6 times 2 on each 10/12 & 3/4 x3 becomes 9/12 so those make 1 7/12 add with 1 and 7
