Find the volume. Round to 1 decimal place

Mathematics
1 answer:
Sedaia [141]3 years ago
4 0

Answer:

380.8cm³

Step-by-step explanation:

Volume of a Cylinder is: V=\pi r^2h

'r' is the radius.

'h' is the height.

We are given a height of 9.9 cm and a diameter of 7cm.

The radius is half the diameter.

Divide 7 by 2:

7/2=3.5

The radius is 3.5 cm.

Solve for The Volume (Using 3.14 for pi):

V=3.14*3.5^2*9.9\\\rightarrow3.5^2=12.25\\V=3.14 * 12.25 * 9.9\\V=38.465 * 9.9\\\boxed {V=380.8035}

380.8035 ≈ 380.8

The volume of the cylinder should be 380.8cm³.

Mandarinka [93]

9514 1404 393

Answer:

  5.2 in

Step-by-step explanation:

An equiangular triangle is also equilateral. All sides will be 6 inches, and the height line will be a perpendicular bisector of the side.

Using trig, the height is ...

  (3 in)tan(60°) = 3√3 in ≈ 5.2 in

Using the Pythagorean theorem, ...

  h² = 6² -3² = 27

  h = √27 ≈ 5.2 . . . inches
