What is the volume of a cone (in cubic inches) with a radius of 2 inches and a height of 3 inches?

2 answers:

8 0

Hello! The formula for the volume of a cone is πr^2h1/3. That means the volume of the cone is 1/3 of the base (squared radius * height * pi). The radius is 2 inches. 2^2 is 4. The height is 3 inches. 4 * 3 is 12. Pi is an irrational number that repeats, but we can use 3.14 as pi. 12 * 3.14 is 37.68. Keep in mind that this is an answer choice, but it is not the answer. We have to divide that by 3 to find the actual area, because the area of the cone is 1/3 of the base. 37.68/3 is 12.56. There. The volume of the cone is 12.56 cubic inches. The answer is A.

345 degrees to a radion

miv72 [106K]

We convert degrees to radian by multiplying by (

$\frac{\pi}{180}$ )

= (345) × ( $\frac{\pi π}{180}$ )

= ( $\frac{345}{180}$ ) × (π)

= 1.9166π

= 1.9166 × 3.14

= 6.018 rad

≈ 6.02 rad

Romashka [77]

17/30 feet
Explanation:
Blue fish: 2/15 feet long
Orange fish: 7/10 feet long

Subtract the orange fish’s length by the blue fish’s:
7/10 - 2/15
Find LCD- 30
Multiply both denominators of each fraction by a number that makes both 30 (whatever that number is multiply that also to both nunerators):
7 • 3 / 10 • 3 = 21/30
2 • 2 / 15 • 2 = 4/30

SUBTRACT:
21/30 - 4/30 = 17/30
FINAL ANSWER: the orange fish is 17/30 feet longer than the blue fish.
