Answer:
12 cm
Step-by-step explanation:
The formula for the area of a trapezoid is written as:
1/2(b1 + b2)h
h = height = 16 cm
b1 = Length of one parallel side = 9cm
b2 = Length of second parallel side = ?
Area of trapezoid = 168cm²
The formula to find the length of the second parallel side =
b2 = 2A/h - b1
b2 = 2 × 168/16 - 9
b2 = 336/16 - 9
b2 = 21 - 9
b2 = 12cm
Therefore, the length of the second parallel side is 12 cm

Answer:-47
Step-by-step explanation:
1# 11+4=15
2# 15+4=19
3# 19+4=23
4# 23+4=27
5# 27+4=31
6# 31+4=35
7# 35+4=39
8# 39+4=43
9# 43+4=47
REMEBER its negative not positive.
12 x 3 = 36
48 - 36 = 12
The 4th side is also 12 feet.
Answer:
9.42
Step-by-step explanation:
Hey There!
The first step of this problem is to find the formula for arc length

r=raduis
0 = angle
now we just plug in the values

so the arc length equals 9.424777961
the last step is to round to the nearest hundreth
so your final answer is 9.42
