Answer:

the total surface area is 40 + 12 + 15 = 67 square units

Step-by-step explanation:

Refer to the diagram:  

the combined area of the top and bottom is 2(5·4) = 40:

the combined area of the ends is 2(1.5·4) = 12; and

the combined area of the front and back is 2( 5 · 1.5) = 15

and so the total surface area is 40 + 12 + 15 = 67 square units

The radius of the circle tangent to sides AC and BC and to the circumcircle of triangle ABC.

r= 24.

<h3>What is the radius of the circle tangent to sides AC and BC and to the circumcircle of triangle ABC.?</h3>

Generally, the equation for side lengths AB is  mathematically given as

Triangle ABC has side lengths

Where

  • AB = 65,
  • BC = 33,
  • AC = 56.

Hence

r √ 2 · (89 √ 2/2 − r √ 2) = r(89 − 2r),

r = 89 − 65

r= 24.

In conclusion, The radius of the circle tangent to sides AC and BC and to the circumcircle of triangle ABC.

r= 24.

Evaluate rs + 14s when r = 6 and s = 8
Ivahew [28]

Answer:

160

Step-by-step explanation:

Plug in 6 for r, and 8 for s in the expression:

(r)(s) + (14)(s) = (6)(8) + (14)(8)

Remember to follow PEMDAS. First, multiply, then add:

(6 * 8) + (14 * 8)

48 + 112

112 + 48 = 160

160 is your answer.
