Answer:
What you need to find is the extra amount of plywood. To do that, you must find the area of the square and the area of the circle and subtract them to find the answer.
Step-by-step explanation:
Formulas:
area of a square: A = bh
area of a circle: A =
square measurements:
b = 28
h = 28
circle measurements:
(≈3.14)
r = 14
A = (28)(28)
A = 784
area of square = 784 in^2
A = 3.14 ()
A = 3.14 (196)
A = 615.44 in^2
784 - 615.44 = 168.56
The amount of plywood left over is 168.56 in^2.
Hope this Helps.
Answer:
DB = 13 cm
Step-by-step explanation:
ΔCAB ≅ ΔDBA by ASA, so CA ≅ DB by CPCTC.
CA = 13 cm, so DB = 13 cm.
Answer:
C = 100 degrees
B = 70 degrees
Step-by-step explanation:
OPPOSITE ANGLES OF A CYCLIC QUADRILATERAL ARE SUPPLEMENTARY, WHENEVER YOU ADD THEM THEY SHOULD GIVE YOU 180 DEGREES.
SOLUTION
A + C = 180
80 + C = 180
C = 100
D + B = 180
110 + B = 180
B = 70
