I NEED HELP WILL MARK BRAINLIEST!!!!!
Luden [163]

Answer:

The volume of cylinder is calculated by:

V = base area x height = pi x radius^2 x height

=>  3617.28 = 3.14 x 12^2 x height

=> 3617.28 = 452.16 x height

=> height = 3617.28/452.16 = 8 (cm)

Hope this helps!

In ΔQRS, the measure of ∠S=90°, the measure of ∠Q=37°, and SQ = 56 feet. Find the length of QR to the nearest tenth of a foot
melisa1 [442]

Answer:

  70.1 ft

Step-by-step explanation:

The cosine relation gives the ratio of the adjacent side to the hypotenuse for an acute angle in a right triangle:

  Cos = Adjacent/Hypotenuse

  cos(37°) = SQ/QR

Rearranging gives ...

  QR = SQ/cos(37°) = (56 ft)/0.798636 = 70.1 ft

The length of QR is about 70.1 ft.

The volume of a Cone = \frac{1}{3} \pi r^{2}h

Since for the ice cream cone has h = 4 inches; r = 0.75; π = 3.14

Then Volume of the Cone = 2.355 in³

∴   This ice cream cone can hold  ≈  2.36 in³ of ice cream without overflowing
