Answer 1

Answer:

Volume of hemisphere =

[tex] \frac{2}{3} \pi \: r {}^{3} [/tex]

Given volume =

[tex]18\pi \: cube[/tex]

[tex] \frac{2}{3} \times \frac{22}{7} \: {r}^{3} = 18 \times \frac{22}{7} [/tex]

So pi is there on both the sides so it will be cut from both LHS and RHS

[tex] \frac{2}{3} \times r {}^{3} = 18[/tex]

[tex]2 \times r {}^{3 } = 18 \times 3[/tex]

[tex]2 \times r {}^{3} = 54[/tex]

[tex]r {}^{3} = \frac{54}{2} [/tex]

[tex]r {}^{3} = 27[/tex]

[tex]r = 3[/tex]

Therefore value of r=3 inches

Find the Area of the shape
(Area of Composite Shapes)

Answers

Answer:

223.5 Km

Step-by-step explanation:

Area = Length x Width

Solving for Square Shape

8 · 6 = 48 km

Area = Length x Width

Solving for Rectangle Shape

9 · 14 = 126 km

Area = Length x Width ÷ 2

Solving for Triangle Shape

11 · 9 = 99 ÷ 2 = 49.5 Km

48 + 126 + 49.5 = 223.5 Km

which angles are complementary to each other ? select all that apply

Answers

Answer: ∠1 and ∠5

Step-by-step explanation:

You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.

Hope this helps :)

Angle 1 and Angle 5 are complementary because the sum of both of those angles equals 90 degrees and the other 3 angles cannot be complementary to each other because they are already 90 degree angles by themself

IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.

With triangles;

The number of triangles is always 2 less than that that of its sides.

= 3 triangles + 2 = 5 sides.

The sum of interior angles

(n-2) x 180 = 540 degree

5-2 x 180

To determine the amount of sides; we remember

(n-2) 180

360 = (n-2) 180

+360 = 180 -360 +180

+360 = 180 = (3 triangles with 180)

900/180 = 5 sides.

If we say 5 triangles created with 3 given lengths

then same rule applies n-2 (180)

=7 sides

HELP!

Answers

Answer:

If R = 1, ~12.57 is the y. (r is the x.)

If R = 2, ~50.27

If r = 3, ~113.1

If r = 4, ~201.06

Step-by-step explanation:

The formula of a cone is pi * r^2 * h/3

If r = 1, we have pi * 1^2 * 12/3

12/3 = 4

and 1^2 = 1

pi * 1 * 4

4 * pi = ~12.57

if r  = 2, we have an imrpoved formula,

pi*2^2 * 4  (h/3 became 4 since 12/3 = 4)

2^2 = 4

4*4 = 16

pi * 16 = ~50.27

If r = 3

our formula is pi*3^2*4

3^2 = 9

pi*9*4

9*4 = 36

36* pi = ~113.1

If r = 4,

our formula is

pi*4^2*4

4^2 = 16 and 16*4 = 64

pi*64 = ~201.06.

Answer:

If R = 1, ~12.57 is the y. (r is the x.)

If R = 2, ~50.27

If r = 3, ~113.1

If r = 4, ~201.06

A square pyramid. The square base has side lengths of 5 feet. The 4 triangular sides have a base of 5 feet and height of 6 feet.
What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?

Answers

Answer:

85 ft^2

Step-by-step explanation:

Ok, the square base area is 5 x 5 = 25 square feet

the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.

To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.

15 x 4 = 60 + 25 = 85 square feet

85 ft __________

find surface area of the prism pls!!!!! explain too. I really need help!!!

Answers

i believe you have to multiply meaning 6x5x2 it’s 60.

Answer: 104 square inches

Step-by-step explanation:

The surface area of a prism is the sum of the surface are of all of it's faces.

We can turn that into this equation SA =  2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.

Substitute to get this:  SA =  2(6 x 2) + 2(2 x 5) + 2(6 x 5)

Simplify with multiplication to get this: SA = 24 + 20 + 60

Simplify with addition to get this: SA = 104

Add the unit label and you get 104 square inches.
