add the volume of a cone, V=1/3 pi times radius squared times h. The volume of the cone is V=355. Then you add the volume of the cone to the volume of the cylinder. the formula for the volume of a cylinder is V= pi times radius squared times h. So the volume of the cylinder will be V=923. if you add those two together the overall volume is 1,278.
Area of a circle with diameter 14.
That means the radius is r=7 and the area is of course πr²
Answer: 49π
Answer:
I think A, but i'm not the smartest
Step-by-step explanation:
Everyone got a calculator.....each weighed 16 oz.......gave them to 20 students.....20 * 16 = 320 total oz
16 oz = 1 lb
320/16 = 20 lbs <==
or, if u just think about it...u gave 16 oz to each student.....16 oz = 1 lb...so u gave 1 lb to each student....20 students = 20 lbs
