Answer:
5/3
Step-by-step explanation:
Answer:
= - 3n - 3
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 6 and d = a₂ - a₁ = - 9 - (- 6) = - 9 + 6 = - 3 , then
= - 6 - 3(n - 1) = - 6 - 3n + 3 = - 3n - 3
Circumference, C is 31.42 units and Area, A is 78.55 sq. units
Step-by-step explanation:
- Step 1: Find C when π = 3.142 and r = 5
C = 2πr = 2 × 3.142 × 5
= 31.42 units
- Step 2: Find A when π = 3.142 and r = 5
A = πr² = 3.142 × 5² = 3.142 × 25
= 78.55 sq. units
HEY THERE !!
As we know that the area of a circle (A)= πr^2
But if we know the diameter then the area is (A)= π/4× D^2 { here D is for diameter}
Here diameter is 10.5 inches.
A => π/4 × (10.5)^2
A => π/4 × 110.25
A => π/4 × 27.5625
A => 86.54625 { because the value of π = 3.14}
So the area of the cirsle whose diameter is 10.5 inches is 86.54625 inches square.
HOPE IT HELPED YOU.
