Jude says that the volume of a square pyramid with base edges of 12 in and a height of 10 in is equal to the volume of a cylinder with a radius of 6.77 in and a height of 10 in. Jude rounded his answers to the nearest whole numbers. Examine Jude's calculations. Is he correct?

Volume of Square Pyramid Volume of Cylinder
V = one third B(h) V = one thirdπr2h
V = one third(144)(10) V = one thirdπ(6.772)(10)
V = one third(1440) one thirdπ(45.8329)(10)
V = 480 in3 V = one thirdπ(458.329)
V ≈ 480 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 cylinder.
Yes, but he made a mistake in solving for the volume of the square pyramid.
No, he made a mistake in solving for the volume of both figures.

No, he made a mistake in solving for the volume of the cylinder.

Step-by-step explanation:

Volume of pyramid:

⅓ × 12² × 10 = 480 in³

Volume of cylinder:

π × 6.77² × 10 = 1439.15406 in³

QUESTION:

solve : 2(5x + 3) = 25

SOLUTION:

▶️2(5x + 3) = 25

▶️ 2 × 8x = 25

▶️ 16x = 25

▶️ x = 25/16

▶️ x = 1.5625

ANSWER:

1.5625
