Q. Find the radius or height. Use 33.1414 for π \pi and round your answers to the nearest hundredth where necessary.\newlineFind the radius of a cylinder with a volume of 950in3 950 \mathrm{in}^{3} and a height of 10in 10 \mathrm{in} .\newline\square
  1. Identify Formula and Values: Identify the formula for the volume of a cylinder and the given values.\newlineThe formula for the volume of a cylinder is V=πr2hV = \pi r^2 h, where VV is the volume, rr is the radius, and hh is the height. We are given the volume V=950in3V = 950 \, \text{in}^3 and the height h=10inh = 10 \, \text{in}.
  2. Plug Known Values and Solve: Plug the known values into the volume formula and solve for the radius rr. We have 950=πr2(10)950 = \pi r^2(10). To find rr, we need to divide both sides of the equation by π\pi and then by the height (1010 in).
  3. Perform Division to Isolate r2r^2: Perform the division to isolate r2r^2. \newline950(π10)=r2\frac{950}{(\pi \cdot 10)} = r^2\newlineUsing 3.143.14 for π\pi, we get:\newline950(3.1410)=r2\frac{950}{(3.14 \cdot 10)} = r^2\newline95031.4=r2\frac{950}{31.4} = r^2
  4. Calculate r2r^2: Calculate the value of r2r^2.95031.4=r2\frac{950}{31.4} = r^2r230.25477707r^2 \approx 30.25477707
  5. Take Square Root to Solve for rr: Take the square root of both sides to solve for rr.r=30.25477707r = \sqrt{30.25477707}r5.50 in (rounded to the nearest hundredth)r \approx 5.50 \text{ in} \text{ (rounded to the nearest hundredth)}
