Answer:

We know, Surface area of a rectangular prism = 2(wl + hl + hw)

area = 2(7*13 + 6*13 + 7*6)

area = 2(91+78+42)

area = 2(211)

area = 422 in²

So, your final answer is 422 in²

Hope this helps!

What is the volume of a cone with a diameter of 30 feet and a height of 60 feet use 3.14 for pie
Nesterboy [21]

Answer:

14,130 feet³

Step-by-step explanation:

2r=d

2r=30

r=15

Formula for the volume of a cone is: \frac{1}{3} *b*h

\frac{1}{3} *π*r²*h=

\frac{1}{3} *3.14*15^{2} *60=\\

\frac{1}{3} *3.14*225*60=

\frac{1}{3} *3.14*13,500=\\

\frac{13,500}{3} *3.14=\\

4500*3.14=

14,130 feet³

Helppppppppppppppppppppppppp
Rasek [7]

Answer:

A  40

Step-by-step explanation:

We can find angle K

J + K + L = 180  The angles of a triangle add to 180

50 + K + 90 =180

140 +K = 180

Subtract 140 from each side

140-140 + K = 180-140

K = 40

Since the triangles are congruent

J = P

K = N

L = M

We want to find N

K = N = 40

K = N

Consider the geometric sequence below.
vladimir1956 [14]

Answer:

f(1) = 8

Common ratio: 0.5

Step-by-step explanation:

f(1) means the firs term in a sequence.

In the function f(n), represented by 8, 4, 2, 1, .., the first term is 8.

f(1) = 8

To find the common ratio, divide any term by the term before it.

We can use any two of the given terms in the sequence EXCEPT for 8 because it is the first term and does not have a term before it.

I choose to divide the second term by the first term:

4/8 = 1/2 = 0.5
