Answer:
27π cm²
Step-by-step explanation:
step 1
Find the area of the complete circle
The area of the circle is equal to
A=πr²
we have
r=9 cm
substitute
A=π(9)²=81π cm²
step 2
Remember that the area of complete circle subtends a central angle of 360°
so
using proportion
Find the area of a sector formed by a central angle that measures 120°
81π/360°=x/120°
x=120°*81π/360°
x=27π cm²
Answer:
Step-by-step explanation:
g(-7) = -7 + 2 = -5
the answer is 1/8. I double checked
Answer:
2
Step-by-step explanation:
Use the intercept method. Where is y when x = 0?
1.25
7 + (10 − 4)2 ÷ 4 × 1 over 2 to the power of 3
7+ (6)2÷ 4 × 1 over 2 to the power of 3
7+ (12)÷ 4 × 1 over 2 to the power of 3
7+3 × 1 over 2 to the power of 3
10 over 2 to the power of 3
10 over 8
1.25
