Answer: 91.592
Step-by-step explanation:
Answer:
The answer is 8 .
Step-by-step explanation:
f(x)=36
36=3x+12
36-12 and 12 -12
36-12=24
24 divided by the 3 that left in the equation equals 8 .
36=3x+12
-12 -12
24=3x
divided 24 by 3 and get 8
Answer:
seventh interior angle=∠x=29°
Step-by-step explanation:
sum of interior angle of polygon is equal to 360°
let seventh angle of heptagon is x
∠x+47°+55°+62°+64°+54°+49°=360°
∠x=360°-(47°+55°+62°+64°+54°+49°)
∠x=360°-331°=29°
∠x=29°
seventh interior angle=∠x=29° answer
Answer:
x=45
Step-by-step explanation:
add (3x-9)+30+24=180
subtract 30 and 24 from both sides
(3x-9) = 126
+9 on both sides
3x=135
divide by 3 on both sides
x=45
Answer:
The radius 10 cm
Step-by-step explanation:
∵ The volume of the cone = 1/3 πr²h
∵ v = 1256 cm³
∵ h = 12 cm
∴ 1256 = 1/3 π (12) r²
∴ r² = 1256 × 3/12π = 100 cm
∴ r = √100 = 10 cm
