Surface Area Question:

Answers

Answer 1

Answer:

190π (not part of the answer choices)

Step-by-step explanation:

The surface area of a cylinder can be found using the formula below:

[tex]SA=2\pi r^2+\pi dh[/tex] where [tex]r[/tex] is the radius of the base, [tex]d[/tex] is the diameter of the base and [tex]h[/tex] is the height of the cylinder.

Plug in the given values

[tex]SA=2\pi (\frac{10}{2}) ^2+\pi (10)(14)\\SA=2\pi (\frac{100}{4})+140\pi\\SA=2\pi (25)+140\pi\\SA=50\pi+140\pi\\SA=190\pi[/tex]

Therefore, although this answer isn't one of the choices, the surface area of the cylinder is 190π.

I hope this helps!

Answer:

45/8 or 5 5/8

Step-by-step explanation:

2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8.  you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.

Answer:

45/8 or 5 5/8

Step-by-step explanation:

When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.

Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.

                                      Numerators: 9 x 5 = 45

                                      Denominators: 4 x 2 = 8

So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.

I don't know how you wanted me to show my work, but I tried the best I could to explain.

B = 12.8 cm (to 1.d.p)

D = 24.1 cm (to 1.d.p)

Step-by-step explanation:

Using Pythagoras Theorem:

B: 4^2 + 3.5^2 = 28.25

square root 28.25 = 5.3 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle B = 12.8 cm (to 1 decimal place)

D: 10^2 - 6.5^2 = 57.75

square root 57.75 = 7.6 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle D = 24.1 cm (to 1 decimal place)

. A fishing bobber has a radius of 0.5 inch. Find the volume of the fishing bobber. Round your answer to the nearest tenth.

Answers

Given:

The radius of the fishing bobber = 0.5 inch.

To find:

The volume of the find bobber.

Solution:

We know that the shape of fishing bobber is a sphere.

The volume of a sphere is:

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Substitute r=0.5 and [tex]\pi=3.14[/tex] to find the volume of the fishing bobber.

[tex]V=\dfrac{4}{3}(3.14)(0.5)^3[/tex]

[tex]V=\dfrac{4}{3}(3.14)(0.125)[/tex]

[tex]V=0.52333...[/tex]

Approx the value to the nearest tenth.

[tex]V\approx 0.5[/tex]

Therefore, the volume of the fishing bobber is 0.5 cubic inches.

The blueprint for an office building uses a scale of 2 cm.:3.5 m. The height of the actual office building is 259 m. What is the height of the office building on the blueprint?

Answers

Answer:

150 cm

Step-by-step explanation:

So the scale is 2 cm on the blueprint = 3.5 meters in real life.

Basically you can just divide the height of the building by 3.5 meters:

259/3.5=75

There are 75, 3.5 meters in 259 meters

Since 3.5 meters on the print is 2 cm

You need to multiply the number of 3.5 meters by 2:

75*2=150

150 cm
