Answer:
x = 7.3
Step-by-step explanation:
area = base × height / 2
21.9 = 6 × x / 2
43.8 = 6x
x = 7.3
Pi is commonly written as 3.14 even though it has an infinite decimal point value. 3pi multiplied by d (which d equaling 12pi) is our expression. Pi = 3.14. 3 x 3.14 = 9.42. 12 x 3.14 = 37.68. The expression is now 9.42 multiplied by 37.68. 9.42 x 37.68 = 353.8456.
Your answer is 30.31
