Answer:
31.8 in^2
Step-by-step explanation:
The area of a circle is pi×radius^2.
r=.5d=18/2=9
A=(3.14159)(9^2)=(3.14159)(81)=254.5
And if each peice is of equal area, the area of one peice will equal:
254.5/8=31.8
Answer:
2x² - 3x
Step-by-step explanation:
multiply the outside with the inside brackets
x × 2x = 2x²
x × (-3) = -3x
Answer:
No answer is equal to 393,500
Step-by-step explanation:
You can try to solve each question.
0.3935 × 10 -6 = -2.065
39.35 × 10 -4 = 389.5
3.935 × 10 -5 = 34.35
3.935 × 10 +5 = 44.35
None of these equal to 393,500

Answer:
-19
Step-by-step explanation:
2×2-2z4+y2-x2+z4
now we put the value,
4-2(2to the power 4)+(3 to the power 2)-(-4 to the power 2)+(2 to the power 4)
4-2×16+9-16+16
4-32+9
4+9-32
13-32
-19
please check the answer again i am sorry if it's wrong
