Answer:
33.30 units²
Step-by-step explanation:
Central angle = m<BCD = 106°
Radius (r) = 6 units
Area of sector BCD = central angle/360° × πr²
Plug in the values into the formula
Area of sector BCD = 106/360 × π × 6²
Area of sector BCD = 106/360 × π × 36
Area of sector BCD = 33.3008821
Area of sector BCD = 33.30 units² (nearest hundredth)
X^+5x would be the answer
Answer:
you multiply the second equation by -2.
Step-by-step explanation:
to get rid of y and find x. Then you plug x into one of the equations to find y
Answer:
3.
Step-by-step explanation:
3m^2-3n^2= 3(m^2-n^2) = 3 (m+n)(m-n)
6m-6n= 6 (m-n)
3(m+n)~(m-n)~/6~(m-n)~ = (m+n)/2
C=2pir
c=25.12
25.12=2pir
divide both sides by 2
12.56=pir
divide both sides by 3.14 since we will use pi=3.14
4=r
radius is 4cm
