Answer:

The answer to your question is below

Step-by-step explanation:

1.- Find the volume of the cylinder

Data

diameter = 9 cm

radius = 4.5 cm

height = 15 cm

Formula

   V = πr²h

   V = π(4.5)²(15)

  V = 303.75π         This is te answer for the volume in terms of π

       = 952.78 cm³                

2.- Find the volume of the cylinder

height = 40 yd

radius = 12 yd

Formula

   V = πr²h

   V = π(12)²(40)

   V = 5760π              This is te answer for the volume in terms of π

       = 18086.4 cm³

3.- What is the height .......

height = q

side length = r

4.- Volume of a pyramid

    Volume = Area of the base x height

Area of the base = 11 x 11 = 121 cm²

    Volume = 121 x 18

   Volume = 2178 cm³

Answer:

1. 953.775 cm³

2. 18,086.4 yd³

3. height: q ; side: r

4. 726 cm³

Step-by-step explanation:

1. Volume = pi × r² × h

= 3.14 × (9/2)² × 15

= 953.775 cm³

2. Volume = pi × r² × h

= 3.14 × 12² × 40

= 18086.4 yd³

3. height: q ; side: r

4. Volume = ⅓ base area × height

= ⅓ × 11² × 18

= 726 cm³

Are the two triangles similar?
Tpy6a [65]

Answer:

Option B Yes by AAA

Step-by-step explanation:

we know that

If the two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

so

\frac{HM}{MK}=\frac{GM}{MJ}

substitute the values and verify

\frac{8}{12}=\frac{6}{9}

simplify

\frac{2}{3}=\frac{2}{3} -------> is true

therefore

The triangles are similar by AAA------> the three angles are congruent

Steven has a rectangular rug with a perimeter of 16 feet. The width of the rug is 5 feet. What is the length of the rug?
boyakko [2]
\boxed{\boxed{\text{Perimeter = 2(Length + Width)}}}

Given that the perimeter is 16ft and width is 5 ft,
16 = 2( Length + 5)

Distribute 2:
16 = 2Length + 10

Take away 10 from both sides:
2Length = 16 - 10

Evaluate the right hand side:
2Length = 6

Divide by 2 on both sides:
Length = 3

\boxed{\boxed{\text{Answer: Length = 3 ft}}}

ONLY ANSWER IF UR CORRECT PLZZ!
anyanavicka [17]

Answer:

∠4 & ∠8

∠3 & ∠7

Step-by-step explanation:

When the transversal (the line that crosses the other 2) intersects through 2 lines, it forms 2 pairs of alternate interior angles.

The alternate interior angles are always located in the inner corners of the intersections and are on opposite ends of the transversal.

The surface area of the cone is: A. 184π units².

<h3>What is the Surface Area of a Cone?</h3>

Surface area of a cone = πr(l + r), where r is the radius and l is the slant height.

Given the following:

  • Slant height (l) = 15 units
  • Radius = (r) = 8 units

Surface area of a cone = π8(15 + 8)

Surface area of a cone = 184π units²
