Answer:

114 m²

Step-by-step explanation:

a² + b² = c²

a=3, b=8/2=4

3² + 4² = 9 + 16 = 25 = c²

c = 5

B. 3/16
C. 5/16
D. 7/16

Answers

d. 7/16
i think its that because 4 plus 3 equals 7 and they asked second or third row and they only have second row up there and they asked for both so i think 7/16.
The answer is D.7/16 due to the fact that there are 4 students in the second row, and 3 students in the third, the ratio would be 7/16.hope i helped.

H 24 inches The volume of a cylinder can be found by using the formula v Bh. Which expression can be used to determine B, the area of the base of this hatbox in square inches? (24) H 82.12 J 122.8

Answers

The volume a cylinder is v=(area of base)h and since the area of the base is πr², you can write the equation a v=πr²h.  Since the problem wants us to find what be is in the equation of a cylinder as v=Bh, we know that B=πr².  The problem gave us the diameter of the circle so we no the radius is going to be the diameter (24) divided by 2 which equals 12.  therefore B=12²π.
