Since the triangle is a right triangle, we can use the pythagorean theorem to solve for the one remaining side.
Plug in your values
a = 9
b = ?
c = 15
9^2 + b^ = 15^2. Square root 9 and 15
81 + b^2 = 225. Subtract 81 from each side.
b^2 = 144. Take the square root of each side.
b = 12.
Now we know the length and width of the rectangle.
Perimeter = 2(12 + 9)
Perimeter = 42 in
Answer:
Volume increasing rate =
Explanation:
We rate of change of radius of sphere,
Diameter of sphere = 100 mm
Radius of sphere = 50 mm
Volume of sphere, V =
Rate of change of volume =
Substituting known values
Volume increasing rate =
(Bc)/(ab)=tan1
(Ef)/(ec)=tan2
Angle 1= angle 2
Tan1=tan2
(Bc)/(ab)=(ef)/(ec)
...
It would take 471 weeks. First, square the radius. Then divide the height by three. Multiply the square radius and the answer you got after dividing h by 3. Then multiply that answer by 3.14. Usually, you're done, but for this problem take the extra step and divide it by 12,000.
