If you are given the volume then
V=(1/3)hpir^2
h=height
r=radius
V=volume
solve for r

times 3 both sides
3V=hpir^2
dvivide both sides by hpi
\frac{3V}{h \pi}=r^2
sqrt both sides
\sqrt{\frac{3V}{h \pi}} =r

Multiply the volume by 3.
Multiply the height by π, which is a numeric constant that begins 3.14 and never terminates.
<span>Divide the tripled volume by the product of the height and π.
</span><span>Find the square root of the result from the 3rd step

The measure of the supplement of an angle is seven times as large as the measure of its complement find the measure of the angle
8090 [49]

Answer: original angle = 75°

Its supplement 105°

Its complement = 15°

Step-by-step explanation:

We know that,

  • Sum of supplementary angles is 180 degrees.
  • Sum of complementary angles is 90 degrees.

Let x be the original angle , then its supplement = 180° - x

its complement = 90° - x

As per given,

180° - x = 7(90° - x)

⇒ 180° - x = 630° - 7x

⇒  7x- x = 630° -180°

⇒  6 x = 450°

⇒  x = 75°  [divide both sides by 6]

So, original angle = 75°

Its supplement =  180° - 75° = 105°

Its complement = 90° -75° = 15°

Hence,  original angle = 75°

Its supplement 105°

Its complement = 15°

So 10.38 gal at 2.289 oer gal but you want american mony so round 2.289 to two decimal places so 2.29 per gallon

2.29 times 10.38=23.7702 but you just cross out the '2' in the ten-thousanth's place because 1/50 of a cent is really small


it is not possible to pay 9/10 of a cent so they just want you to round it up to 1 cent or10/10 cent
