Answer:
degree = 120°
A =67 cm²
d=?
note : diameter= 2×radius
area of a circle = πr²
67=22/7 ×r²
67×7=22r²
469=22r²
r²=469/22
r²=21.32
r=4.62
diameter=2 × radius
d= 2× 4.62
d=9.24
d=9
I hope it helps :)
Answer:
x = 3
Step-by-step explanation:
(x - 1)2 = 4
how to get this solved is very simple.
first step to apply is the BODMAS RULE
B..................... bracket
O..................... of
D.....................Division
M.................... multiplication
A..................... addition
S.................... Subtraction
so (x - 1)2 = 4
we have,
2x - 2 = 4 ( by opening the bracket)
collect the like terms
2x = 4+2
divide both sides by 2
2x/2 = 6/2
x = 3
to check if your answer is correct put the value of x = 3 into the question and see if the right hand side will equal to the left handside
(x - 1)2 = 4
(3-1)2=4
2(2)=4
4=4.............................. proved
