Answer:
The approximate volume of the tank is 
Step-by-step explanation:
we know that
The volume of a hemisphere (water storage tank) is equal to

we have

assume

substitute


<span>m∠3 = 180 -(x + x - 6 )
= 180 - 2x + 6
= 186 - 2x</span>
The angle that subtends a chord is half the measure of the arc, so we have an arc QS of 2(84)=168 degrees.
Answer: 168 degrees
Answer: (4+1)*5=25; (25+1)*5=130; (130+1)*5=655.
Step-by-step explanation:
Perimeter = 2(length + width)
59 = 2(14+x)
59 = 28 + 2x
31 = 2x
15.5 = x
Width = 15.5
