It is generally useful to use the formula. The procedure is to substitute the given values for the variables in the formula, then do the arithmetic.
... A = (1/2)r²·θ . . . . r is the radius, θ is the central angle in radians
Put the numbers in ...
... A = (1/2)(4 in)²·(π/3)
... A = 8π/3 in² ≈ 8.37758 in²
Answer:
a = 21 or -21
Step-by-step explanation:
Either a/7 = 3 meaning a = 21
<u> OR </u> a/7 = -3 meaning a = -21
Answer:
I'll edit my answer when you give more context, but for now, say you knew the values of A and B. Say A is 3 and B is 13. In order to find out C you'll need to subtract A from B; 13-3=10. C=10 in this situation.
Okay !! what’s the question ?
B. 1,147, I’m not quite sure
