Answer:
Area of shaded part = 41.09733550
Perimeter of shaded part = 35.82011867
Step-by-step explanation:
Area of shaded part = ((πr^2) 4) - (bh ÷ 2)
Area of shaded part = ((π(12)^2) ÷ 4) - ((12)(12) ÷ 2)
Area of shaded part = (452.3893421 ÷ 4) - (144 ÷ 2)
Area of shaded part = (113.0973355) - (72)
Area of shaded part = 41.09733550
Perimeter of shadedpart:
AC = √a^2 + b^2
AC = √12^2 + 12^2
AC = √144 + 144
AC = √288
AC = 16.97056275
Perimeter of whole circle ÷ 4:
C=2πr
C=2π(12)
C=75.39822369
C ÷ 4 = 75.39822369 ÷ 4
C ÷ 4 = 18.84955592
<em>Perimeter of shaded part: </em>
18.84955592 + 16.97056275 = 35.82011867
Answer:
D
Step-by-step explanation:
Multiply 4 to each number
Answer:
x = - 16
Step-by-step explanation:
Given
x + 7 = - 9 ( subtract 7 from both sides )
x = - 16
Combine: -4 (33y+2)/ 23
simplify: -132y/23 -8/23
:D hope i helped
