What is the converse of t &gt; r
Anettt [7]

The converse of  t > r is r > t

<h3>What is a converse statement?</h3>

A converse statement is determined when both the hypothesis and conclusion are reversed or interchanged.

In this condition, the hypothesis is written as the conclusion and the conclusion is changed to be the hypothesis.

If a conditional statement is written as: x → y

The converse is then written as y → x

Where;

  • x is the hypothesis
  • y is the conclusion

Given the expression as;

t > r

We can see that;

  • The variable 't' is the hypothesis
  • The variable 'r' is the conclusion

The converse will be;

r > t

Hence, the converse is r > t

Volume of right trapezoid cylindar whole bases are B 16m, b 8m, height is 4m and length is 32m
viktelen [127]

Answer:

volume = 1536 m^3

Step-by-step explanation:

given data;

B = 16m

b =8 m

height   H = 4 m

length  L = 32 m

volume of any right cylinder = (Area of bottom) \times (length)

Volume = A* L

The area of a trapezoid is

A=\frac{1}{2} H*(b+B)

A =\frac{1}{2} 4*(8+16)

A = 48 m^2

therefore volume is given as  

volume = 48*32

volume = 1536 m^3
