NEED HELP ASAP. 1.the radius of a cylindrical construction pipe is 2 feet if the pipe is 21 ft long .what is its volume? use the value 3.14 for pi and round your answer to the nearest whole number 2.find the volume of a cone with a base diameter of 12 yd and a height of 10yd. do not round and use 3.14 for pie

1.    263 ft²                2.        376.8 yds²

Step-by-step explanation:

1.   V=3.14r²h                 Use this equation to find the volume of a cylinder

V = 3.14(2)²(21)              Multiply

V = 263.76 = 263 ft²

2.                   Use this equation to find the volume of the cone

                 Multiply

V = 376.8 yds²

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
