Ans
B,D,F
Step-by-step explanation:
Y=5-x^2
Y=3x^2+1
Y=x^3
7.85+q≤ -18.15
Simplify both sides of the inequality
q+7.85 ≤ -18.15
Subtract 7.85 from both sides
q+7.85-7.85 ≤ -18.15-7.85
Q ≤ -26
I hope that's help !
Answer:
Step-by-step explanation:
Answer:
<u>42.25π m²</u>
Step-by-step explanation:
Let's solve!
⇒ Take the radius of the lawn to be 'r'
===========================================================
Then, area of the path equals :
⇒ Area of (lawn + path) - Area of lawn
⇒ π (r + 2)² - πr² = 30π
⇒ πr² - πr² + 4πr + 4π = 30π
⇒ 4πr = 26π
⇒ r = 6.5 m
===========================================================
Area of the lawn :
⇒ Area = πr²
⇒ Area = π × (6.5)²
⇒ Area = <u>42.25π m²</u>
