Help please

1016 cm^2

Step-by-step explanation:

2 Triangular ends: 12×14=168 each. +336

2 sides 10×25=250 each. +500

1 base 10×14= 140. +140

Add all parts:. 336+500+140=976 square centimeters.

I hope you see how this works.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
