Answer:

  • h =  V/πr²
  • h = 10 inches

Step-by-step explanation:

  • V = πr²h

<u>1. Solving for h:</u>

  • V = πr²h
  • πr²h = V
  • πr²h/πr² = V/πr²
  • h =  V/πr²

<u>2. Finding the height of given cylinder, using formula above:</u>

  • V = 90π, r = 3 inches, h = ?
  • h =  V/πr²
  • h = 90π/π3²
  • h = 10 inches

Answer:

∠ ABC = 22°

Step-by-step explanation:

OA = OB ( radii of circle )

Then Δ OAB is isosceles with base angles congruent , that is

∠ OBA = ∠ OAB = 17x

The sum of the 3 angles in the triangle sum to 180°

17x + 17x + 11x = 180

45x = 180 ( divide both sides by 45 )

x = 4

Then

∠ OBA = 17x = 17(4) = 68°

BC is a tangent so ∠ OBC = 90°

∠ ABC = 90° - ∠ OBA = 90° - 68° = 22°

When the expression 10^2021 − 2021 is evaluated, the result is a very large number.
Dafna11 [192]

Answer:

18,176

Step-by-step explanation:

Figure out an easier thing to do: 1000 - 2021 = 9,797.

Therefore, our answer will be like 9999999999999999999999997979. Out of all of these digits, there are only 2 that arent nines. We know the amount of digits since it's 10^2021 power. We will have one less since we are subtracting 2021. Therefore, 2020 digits in total. Now we know of those 2020 digits, 2 of them are 7, therefore 2018 of them are 9s. That means do 2018(9) + 2(7) = 14 + 18,162 =  18,176.

Sindrei [870]

one interior angle = 30° <==== this one is given

second interior angle = 180 - 40 = 140° <=== interior angle + exterior angle = 180

third interior angle = 180 - 30 - 140 = 10° <=== angles in a triangle = 180
