What is the surface area of the right cone below?

Mathematics
1 answer:
stellarik [79]3 years ago
7 0

Answer:

A. 68 units2

Step-by-step explanation:

First of all to solve this problem we have to know the formula to calculate the surface area of the cone

A = area

r = radius  = 4

L = 13

π = pi  

A = π*r² + π*L*r

we replace with the known values

A = π *  (4u)² + π * 13u * 4u

A = 16π u² + 52π u²

A = 68π u²

The surface area of the cone is 68π u²

kogti [31]

Given that plane P is parallel to the planes containing the base faces of the prism; then, if the plane meets the prism between the planes containing the hexagonal bases, then P meets the prism in a hexagonal region that is congruent (with the same size) to the bases of the prism.

Simplify 3[2^3 + (4-2)^3 - (6-2)^2]
Ivahew [28]

Answer:

\boxed{0}

.

Step-by-step explanation:

3(2^3 + (4 - 2)^3 - (6 - 2)^2)

= 3(2^3 + 2^3 - 4^2)

= 3(2.2^3 - (2^2)^2)

= 3(2^4 - 2^4)

= 3(0)

= 0

-7–5(3g+8)&lt;10g–7+g <br><br> help me please!
Ede4ka [16]

Answer:

-20/13 <g

Step-by-step explanation:

-7–5(3g+8)<10g–7+g

Distribute

-7–15g-40<10g–7+g

Combine like terms

-15g - 47 < 11g -7

Add 15 g to each side

-15g+15g -47< 11g+15g -7

-47 < 26g -7

Add 7 to each side

-47+7 < 26g-7+7

-40 < 26g

Divide each side by 26

-40/26 <26g/26

-40/26 <g

Divide top and bottom by 2

-20/13 <g

Find the distance between the points with coordinates (-26,0) and (95, 0).
mote1985 [20]

Answer:

0

Step-by-step explanation:

Distance between two points is the slope .

Slope =change in y/change in x

Given (-26,0) and (95,0)

x1 = -26

y1 = 0

x2 = 95

y2 = 0

Slope = y2 - y1 / x2 - x1

0-0/95-(-26)

0-0/95+26

0/121

0
