Answer:
20.8 ft²
Step-by-step explanation:
area = (ab sin C)/2
area = (6 ft × 8 ft × sin 60°)/2
area = 20.8 ft²
Answer:
D) 25.5 cm
Step-by-step explanation:
Circumference = pi × d
20 = 3.14 × d
d = 6.3694267516
Diameter = length of one side
Perimeter of the square = 4s
4(6.3694267516)
25.4777070064 cm
From the options, closest is 25.5
Well the first part is 27 but the second part is adding 60 to 21 which is 81. dont forget that!
Find a common denominator which is 12
1*3=3 4*3=12 so 3 3/12
then 5*2=10 6*2=12 so 2 10/12
2 10/12+3 3/12= 5 13/12
13/12= 1 1/12 plus 5= 6 1/12
so your answer would be 6 1/12
