Here's the equation for the area of a semicircle: A = (πr²)/2

Based on this, let's solve for this area in terms of π (pi):

A = π(10²)/2 = 100π/2 = 50π

The area of the semicircle, I believe, is 50π. Hope this helps, let me know if I messed up!

Answer: A=157

Step-by-step explanation: The area of a semi-circle can be found using the radius in the formula A=1/2 $\pi$ r^2. We substitute the radius in the equation A=1/2*3.14*10^2

First we do the exponents following pemdas.

A=1/2*3.14*10^2

A=1/2*3.14*100

Then we multiply.

A=1/2*3.14*100

A=1.57*100

A=157

The final answer is 157.

Hope this helps!

R=6.57978

also everyone add my sc- amber_hughes42

Step-by-step explanation:

we are given

I=3.8 \times 10^6

I_0=1

now, we can use formula

R=log(\frac{I}{I_0} )

now, we can plug these values

we get

R=log(\frac{3.8 \times 10^6}{1} )

Two consecutive negative integers have a product of 12. What are the integers?

iVinArrow [24]

Well 12 = 3×4 thus answer would be -3 and -4

For algebra solution, we can let smallest integer be n then that would be n(n+1) = 12, so we can go ahead and solve for n:

n(n+1) = 12

n² + n - 12 = 0

(n-3)(n+4) = 0

n = 3 or -4

Since we need negative integers, n would be -4 and then next integer (n+1) would be -3.

Hope this helps.
