Step-by-step explanation:
For oil container in the shape of a cylinder
radius (r) = 6 m
height (h) = 7 m
TSA of Cylinder
= <em><u>2πr ( r + h) </u></em>
= 2 * 3.14 * 6 ( 6 + 7)
= 2 * 3.14 * 6 (13)
= 2 * 3.14 * 6 * 13
= 489.84 square meter
<em>Now, </em><em> </em>
the total cost of the steel will be $18,613.92.
= 18613.92/489.84
= $38
Thus, The TSA of a cylinder is 489.84 square meter and $38 will the steel cost per square meter.
Step-by-step explanation:
it is the formula to calculate the time
in the formula
t = I / pr
t stands for time.
I stands for interest.
p stands for principal.
r stands for rate.
Hope it helps. :)

(1) ∠ABC = 65°, ∠DBE = 65°, ∠CBE = 115°, ∠ABD = 115°
(2) ∠ABC = 62°, ∠DBE = 62°, ∠CBE = 118°, ∠ABD = 118°
Solution:
(1) In the given image ABC and DBE are vertical angles.
<u>Vertical angle theorem:</u>
If two angles are vertical then they are congruent.
⇒ ∠ABC = ∠DBE
⇒ 3x° + 38° = 5x° + 20°
Arrange like terms one side.
⇒ 38° – 20° = 5x° – 3x°
⇒ 18° = 2x°
⇒ x° = 9°
∠ABC = 3(9°) + 38° = 65°
∠DBE = 5(9°) + 20° = 65°
Adjacent angles in a straight line = 180°
⇒ ∠ABC + ∠CBE = 180°
⇒ 65° + ∠CBE = 180°
⇒ ∠CBE = 115°
∠ABD and ∠CBE are vertical angles.
∠ABD = 115°
(2) In the given image ABC and DBE are vertical angles.
⇒ ∠ABC = ∠DBE
⇒ 4x° + 2° = 5x° – 13°
Arrange like terms one side.
⇒ 13° + 2° = 5x° – 4x°
⇒ 15° = x°
∠ABC = (4(15°) + 2°) = 62°
∠DBE = 5(15°) – 13° = 62°
Adjacent angles in a straight line = 180°
⇒ ∠ABC + ∠CBE = 180°
⇒ 62° + ∠CBE = 180°
⇒ ∠CBE = 118°
∠ABD and ∠CBE are vertical angles.
∠ABD = 118°
