Answer:
A = 307.9 sq/cm
Step-by-step explanation:
Find the radius of the semi-circle
diameter + half the circumference = 72 cm
2r + pi*r = 72
r(2+pi) = 72
r = 72%2F%28%282%2Bpi%29%29
r = 14
:
what will be the area of that semicircle?
A =1%2F2*pi%2A14%5E2
A = 307.9 sq/cm
Your answer is x=1.243927
Answer:
$900
Step-by-step explanation:
a)Off given on purchasing a TV= 20%
20% on TV = $ 180
Let the original price of TV set $ x
According to question,
20% of x= $180
×x= $180
x = $ 180× 5
x= $ 900
Hence, Original price of TV set= $ 900
b) By second method,
20%= $180
1%= $ 9
100% = $900
Hence, the original price $ 900
Answer:
G is not TRUE.
Step-by-step explanation:
using the law A+B = B+A
PYTHAGOREAN THEOREM
A²+B² =C² is equal to B² +A² = C²
So for A²,
B² - c² = A. remember if a positive number move from the left to the right over an equal sign it becomes negative and vice versa
B²
C² - A²= B²
It equal to .3333333333333333333333333333333333......
