Answer:
37.68in
Step-by-step explanation:
circumference = 2πr
r= radius = diameter/2 = 12/2 =6 in
C= 2πr = 2 x 3.14 x 6= 37.68in
Answer:
D
Step-by-step explanation:
step 2 : x + 3 = 0 and x - 5 = 0 ← correct
step 3
x = 3 and x = - 5 ← error made here with signs, correct statement should be
x + 3 = 0 ⇒ x = - 3
x - 5 = 0 ⇒ x = 5
It is (3,5)

The answer to the above equation is 1.1659 *10⁻¹³
Step-by-step explanation:
We can easily do this equation by knowing some basic indices corollary. These include
- aᵇ=1/a⁻ᵇ similarly a⁻ᵇ = 1/aᵇ
- aᵇ.aⁿ = aᵇ⁺ⁿ
- aᵇ/aⁿ=aᵇ⁻ⁿ
Using these three corollaries we can easily solve the equation-
2.6 x 10⁻⁶/ 2.23 x 10⁷
Using the corollary 1, the equation can be rewritten as-
⇒2.6/2.23 ₓ10⁷ₓ 10⁶
Using corollary 2-
⇒2.6/2.23 ₓ 10⁷⁺⁶
⇒2.6/2.23 ₓ 10¹³
Using corollary 1 in reverse manner (1/aᵇ= a⁻ᵇ)
⇒1.1659ₓ 10⁻¹³
Hence the answer of the equation is 1.1659 ₓ 10⁻¹³
