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

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
