The cone and cylinder below have equal surface area
marissa [1.9K]

Answer:

Option B, False

Step-by-step explanation:

<u>Step 1:  Get the surface area formulas for both shapes</u>

Surface Area Formula for Cone:  A = \pi * r(r + \sqrt{h^{2} + r^{2}})

Surface Area Formula for Cylinder:  A = 2\pi rh+2\pi r^{2}

<u>Step 2:  Plug in the values and solve</u>

Cone:  A = \pi * r(r + \sqrt{(3r)^{2} + r^{2}})

Cone:  A = \pi r^{2} + \pi \sqrt{10}r^{2}

Cylinder:  A = 2\pi r*r+2\pi r^{2}

Cylinder:  A=4 \pi r^{2}

<u>Step 3:  Compare</u>

<u />\pi r^{2} + \pi \sqrt{10}r^{2}\neq 4 \pi r^{2}

They are not equal, therefore the answer is False.

Answer:  Option B, False

Paul is making bread using a recipe. The amount of flour he uses is proportional to the number of loaves of bread. He uses 1114
DiKsa [7]

Answer:

$20

Step-by-step explanation:

Paul is making bread using a recipe. The amount of flour he uses is proportional to the number of loaves of bread. He uses 11 1/4 cups of flour to make 5 loaves of bread. If Paul used 18 cups of flour, and then sold the loaves of bread he made at a bake sale for $2.50 each, how much money would Paul make from his bread sales?

Step 1

Find out how many loaves of bread he can produce from 18 cups of flour

11 1/4 cups of flour = 5 loaves of bread

18 cups of flour = x loaves of bread

Cross Multiply

11 1/4 cups × x loaves = 18 cups × 5 loaves

x loaves = 18 cups × 5 loaves/ 11 1/4 cups

x loaves = 90 ÷ 11 1/4

x loaves = 90 ÷ 45/4

x loaves = 90 × 4/45

x loaves = 8 loaves of bread

He can produce 8 loaves of bread from 18 cups of flour.

Step 2

We are told that:

1 loaf of bread costs $2.50

Hence,

1 loaf of bread = $2.50

8 loaves of bread = $x

Cross Multiply

$x = 8 loaves of bread × $2.50

$x = $20

Therefore, Paul made $20 from his bread sales

A regular polygon has an interior angle of approximately 158.8°.
Step2247 [10]

Answer:

  • 17 sides

Step-by-step explanation:

<u>Property of regular polygons:</u>

  • Sum of Interior Angles = (n−2) × 180°, where n is number of sides

<u>In our case we have:</u>

  • 158.8×n = (n - 2)×180
  • 180n - 158.8n = 360
  • 21.2n = 360
  • n = 360/21.2
  • n = 17
