Calculate 4 raise to power 2 multiply by 5 raise to poer 2 minus 18 raise to power 2​

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 !

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
