The cone and cylinder below have equal surface area

marissa [1.9K]

Answer:

Option B, False

Step-by-step explanation:

Step 1: Get the surface area formulas for both shapes

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

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

Step 2: Plug in the values and solve

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: $A=4 \pi r^{2}$

Step 3: Compare

$\pi r^{2} + \pi \sqrt{10}r^{2}\neq 4 \pi r^{2}$

They are not equal, therefore the answer is False.

Answer: Option B, False

Answer:

x=80

Step-by-step explanation:

The sum of interior angles in a quadrilateral is 360°

the square represents a right angle= 90 degrees

124+66+90=280

360-280=80

x=80

3x+9y=75 8x+5y=67 what is x and y?

There are many ways to solve simultaneous linear equations. One of my favorite for finding integer solutions is graphing. The attached graph shows the solution to be ...

... (x, y) = (4, 7)

_____

You can also use Cramer's Rule, or the Vedic math variation of it, which tells you the solution to

$ax+by=c\\dx+ey=f$

is given by

$x=\dfrac{bf-ec}{\Delta}\\\\y=\dfrac{cd-fa}{\Delta}\qquad\text{where $\Delta=bd-ea$}$

Here, that means

... x = (9·67-5·75)/(9·8-5·3) = 228/57 = 4

... y = (75·8-67·3)/57 = 399/57 = 7

_____

A (graphing) calculator greatly facilitates either of these approaches.
