The answer is b. 25.12
because we are finding the amount of rope to go around the circle, we are looking for the circumfrence of the circle, and the formula for the circumfrence of the circle is diameter(pi). because the radius of the circle is 4 inches, the diameter iss 8 inches because the diameter is 2(radius) and using multiplication, we can find the the circumfrence to be 25.12 inches
Answer:
Rhombi and Squares
Step-by-step explanation:
1) KY (pythagorean Thm) 5² + x² = 13² ...= 12
2) PK Diagonals bisected. also = 12
3) Diagonals of rhombi are perpendicular. <YKZ = 90
4) 67. Alternate interior angles are congruent.
5) 3. Diagonals are bisected and congruent for squares.
6) 45° . Angles are bisected by diagonals.
7) 90° . All angles of squares are right angles.
8) 6. Diagonals are bisected. So 3 is doubled to 6.
9) I need graph paper.. hol'up
We know that
x-------------> length rectangle launch tray
w------------< width rectangle launch tray------> 15 cm
<span>length is at least 20% greater than it's width
</span>x>=1.2w---------> x>=1.2*15
the answer part a) is
x>=18 ---------------> (<span> inequality to represent this situation)
part b) </span><span>suppose X is a whole number find the least possible permitted and the least possible area of the lunch tray
</span><span>
the least possible permitted length is 18 cm
</span>the least possible area of the lunch tray is 18*15=270 cm²
