Answer:
18pi, or 56.52
Step-by-step explanation:
To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle
However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:
(pi x radius^2)/2 = area of semi-circle
(pi x 6^2)/2 = area of semi-circle
(36 x pi)/2 = area of semi-circle
18 x pi = area of semi-circle
18 x 3.14 = area of semi-circle
56.52 = area of semi-circle
Answer:
y+7=2(x+10)
Step-by-step explanation:
we find the slope
you can simplify but its already in point slope form
but here it is if you are curious and want to double check it is
y=2x+13
we can also check our work
-7=2(-10)+13
-7=-7
Answer:
17/20
there are 20 different sums but 3 of them add up to 10 and more such as 6+4=10, 5+5=10, 6+5=11
Answer:
x = 115
Step-by-step explanation:
The chord- chord angle x is half the sum of the arcs intercepted by the angle and its vertical angle, that is
x = 
(145 + 85) = 0.5 × 230 = 115
