Answer:

Volume of the cylinder is 75.43

Step-by-step explanation:

Volume of Cylinder is \pi r^{2} h

where r is base radius = 2 and h is the height = 6

(22/7) × 2² × 6

= (22/7) × 4 × 6

= (22/7) × 24

= 528/7

= 75.43

The volume of the cylinder will be 75.4 cubic inches. We figured this out by multiplying Pi x Cylinder Radius^2 x Cylinder Height.

Should be fairly easy..
Harlamova29_29 [7]

Answer:

<u>72 cm²</u>

Step-by-step explanation:

Area of a ∆ = 1/2 × b × h

b = 12 cm

h = 12 cm

Area = 1/2 × 12 × 12

= 1/2 × 144

= <u>72 cm²</u>

If these 2 triangles are similar to each other, the corresponding sides have to exist in proportion to one another. The angles would be exactly the same (side length doesn't matter at all!). Going from the bigger triangle to the smaller, KL corresponds to RS; LJ corresponds to SQ; JK corresponds to QR. The ratio of KL:RS is 5:1; the ratio of LJ:SQ is 5:1; the ratiio of JK:QR is 5:1. That means that the sides are all proportionate and the triangles are similar by the SSS postulate. Now that we know that the triangles are similar, we can say that all the corresponding angles are the same by CPCTC but we had to determinte side similiarity first. Your answer is the second choice, SSS

Step-by-step explanation:

Step 1 : f(2)=3(x)-1

            f(2)=5

Step 2 : f(-2)=3(x)-1

              f(-2)=-7

The function h defined by h(t)=(49 + 4.9t)(10 - t) models the height, in meters, of an object t seconds after it is dropped from
kipiarov [429]

Answer:

Step-by-step explanation:

Let's FOIL this out and get it into standard quadratic format:

h(t)=-4.9t^2+490. The lack of a linear term in the middle means therewas no upwards velocity, consistent with the object being dropped straight down as opposed to thrown up in the air tand then falling in a parabolic path. The -4.9t² represents the acceleration due to gravity, and the 490 represents the height from which the object was dropped. The constant in a quadratic that is modeling parabolic motion always represents the height from which the object was dropped (or launched). That's how you know.
