Answer: Perimeter = 40
Area = 204
Step-by-step explanation:
Perimeter is the sum of all the sides:
11 + 12 + 17 = 40
The area of a triangle is 1/2 base x height
1/2( 17 x 24)
1/2( 408) = 204
201.25 because (175x15)+175=201.25 (i dont know if im right)
Answer:2/6
Step-by-step explanation:
Answer:
Area = 4.5 π cm²
Step-by-step explanation:
Area of semicircle = 
<u><em>Where r = 3cm</em></u>
=> Area = 
=> Area = 
=> Area = 4.5 π cm²
common ratio = a4/a3 = a3/a2
8/a3 = a3/18
(a3)^2 = 8 * 18
(a3)^2 = 144
a3 = 12 or a3 = -12
common ratio = 8/12 or common ratio = 8/(-12)
common ratio = 2/3 or common ratio = -2/3
Answer: 12 or -12
