It’s 45 degrees; since the line is intersecting 2 parallel lines, the angles are the same. similarly, the angle to the right of “angle 2” would be 135 degrees

The volume of a storage tank is 1695.6 m3. The radius is 6m. How tall is the storage tank?

Andreas93 [3]

Answer:

the storage tank is a cylinder.

The formule to calculate the volume is:

$v =\pi{r}^{2} \times h$

$h = v \div \pi {r}^{2}$

$h = 1695.6 \div 36 \times \pi = 14.992$

Write an equation or system of equations to solve the problem below.

VashaNatasha [74]

Equations:

2x+105=-3x+130

subtract 2x from both sides 

105= -5x+130

Subtract 130 from both sides

-5x= -25

isolate the variable

x=5 

Plug back in

2(5)+105= -3(5)+130

115= 115

DiKsa [7]

Answer:

Step-by-step explanation:

The area is calculated by multplying radius (half of diameter) by itself and then with number pi

the area for this circle is given as

144π m^2

144 is the squared form of 12 if the radius is 12 the diameter is 24
