Jude says that the volume of a square pyramid with base edges of 7 in and a height of 7 in is equal to the volume of a cylinder with a radius of 7 in and a height of 7 in. Jude rounded all answers to the nearest whole number. Examine Jude's calculations. Is he correct?

Volume of Square Pyramid Volume of Cylinder
V = B(h) V = r2h
V = 49(7) V = (72)(7)
V = 343 in3 V = 343 in3

Yes, his calculations are correct and the volumes for figures are equal.
No, he made a mistake in solving for the volume of the square pyramid.
Yes, but he made a mistake in solving for the volume of the cylinder.
No, he made a mistake in solving for the volume of both figures.

Jude is not correct , Volume of Square Pyramid ≠ Volume of cylinder

Step-by-step explanation:

volume of a square pyramid with base edges of 9.7 in and a height of 9 in

= 9.7 * 9.7 * 9  inch³

= 846.81 inch³

= 847 inch³

volume of a cylinder with a radius of 5.47 in and a height of 3 in

= π R²H

= 3.14 * 5.47²  * 3

= 281.8 inch³

= 282 inch³

Volume of Square Pyramid ≠ Volume of cylinder

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
