Answer:
16/20
Step-by-step explanation:
Since this is a right triangle
sin theta = opp side / hypotenuse
sin theta = 16/20
Answer:
75.39 in^2
Step-by-step explanation:
circumference=2πr
30.8=2(3.14)r
30.8=6.28r
4.9=r
Now that we know the radius, we can plug it in for the area equation
area=πr^2
area=(3.14)(4.9)^2
area=(3.14)(24.01)
area=75.39 in^2
Answer:
A of each triangular base = 6 in²
A of both bases = 12 in²
Lateral A = 96 in²
Surface area = 108 in²
Step-by-step explanation:
<em>Area of each triangular base</em>
1/2(3)(4) = 1/2(12) = 6
<em>Area of both bases</em>
6*2 = 12
<em>Lateral Area</em>
(8)(3) + (8)(4) + (8)(5)
24 + 32 + 40
96
<em>Total Surface area</em>
96 + 12 = 108 in²
