Diameter of semicircle is equal to 2 km.
<h3>
Explanation:</h3>
Given: Perimeter of semicircle = P = 5.14 km
d=?
Perimeter of semicircle is given by
Simplifying the above equation
As value of pi = 3.14, equation becomes
Diameter of semicircle is equal to 2 km.
Answer:
9108
Step-by-step explanation:
23^3+(-12)^3+(-11)^3 remove parentheses
= 23^3-12^3-11^3 group difference of two cubes
= (23-12)(23^2+23*12+12^2) + 11^3 factor difference of two cubes
= 11 (23^2+23*12+12^2-11^2) factor ou 11
= 11(23(23+12) + (12+11)(12-11)) apply difference of two squares
= 11 (23*35+23*1) factor out 23
= 11(23*(35+1)) simplify
= 11*23*36 convert 11*23 into difference of 2 squares
= (17^2-6^2)*6^2 expand parentheses
= 102^2-36^2 evaluate squares
= 10404 - 1296 subtraction
= 9108

First one is A
Second one is also A
the third one is also A!!!!
DA, AB, BC, CD
square, are side equal length and 90 degree angles
rectangle, two pairs of same length and 90 degree angles
parallelogram, two pairs of same length and two pairs of same angles
rhombus, all sides equal, two pairs of same angles.
yes, because they have the same length of all sides, same shape and same angles.
hope that helps! :D
Answer:
Step-by-step explanation:
Points D, C and A are collinear as DC, CA and DA have same slope of 1/3.
Numerators: 8 and 7 = 56
Denominaters; 7 and 4 =28
Final answer 56/28 or 2
