Answer:
Option A, V = 3 * 5 * 4
Step-by-step explanation:
Volume of a Cube formula: V = w*h*l
Step 1: Plug in
V = whl
V = (5)(4)(3)
Answer: Option A, V = 3 * 5 * 4
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=1/2r^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!
