Answer:
A. 18.84
B. 28.26
C. 364.24
D. 120
E. 14
F. 21
G. 96
CODE: 1977.98
Explanation:
a. C = 2πr
C = 2π(3)
C = 6π
C = 6(3.14)
C = 18.84
b. A = πr²
A = π(3)²
A = 9π
A = 9(3.14)
A = 28.26
c. C = 2π(58)
C = 116π
C = 116(3.14)
C = 364.24
d. 4x + 2x = 180
6x = 180
x = 30
4x = 4(30) = 120
e. 3x - 21 = x + 7
2x = 28
x = 14
f. angle JHK = 3x - 21 = 3(14) - 21 = 21
g. supplementary means 2 numbers add up to 180
180 - 84 = 96
CODE: E(C - D) - F(G - B) - A
14(364.24 - 120) - 21(96 - 28.26) - 18.84
= 14(244.24) - 21(67.74) - 18.84
= 3419.36 - 1422.54 - 18.84
= 1977.98
