Answer:
D 97 cm^2
Step-by-step explanation:
The area of the circle is
A = pi * r^2
We need to convert diameter to r
d =2r
d/2 =r
12/2=r
6 =6
The radius is 6
A= pi *6^2
A = 36 *(3.14)
A = 113.04 cm^2
Now the fraction of the circle that is shaded is 301degrees out of 360
(A circle is 360 degrees)
310/360 * area of a circle
310/360 * 113.04
97.34
Answer:
f=127 cm
Step-by-step explanation:
Law of Cosine:
x squared=92 squared+42 squared-2(92)(42)(cos 141)
x squared =8464+1764-7728(cos 141)
x=127 cm
Answer:
b
Step-by-step explanation:
785.63-(57+125)
=785.63-182
=603.63
603.63+57.25=$660.87
Answer:
Y = -3x - 1
Step-by-step explanation:
Y= mx + b
M is the slope
Y is the y intercept
