The volume of a cone-shaped tunnel is 424 cubic centimeters. The height of the funnel is 5 centimeters. Find the radius of the funnel. Round your answer to the nearest whole number.

volume of cone=424cm³

height(h)=5cm

radius (r)=?

Step-by-step explanation:

we have

volume of cone=1/3(πr²h)

424=1/3(22/7×r²×5)

424×3=15.71r²

r²=1272/15.71

r=√80.9=8.9=9cm

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
