Answer:
Step-by-step explanation:
Sample space = {1, 2 , 3 , 4 , 5, 6, 7, 8, 9, 10}
The constant π is defined as the ratio of the circumference of a circle with respect to its diameter, mathematically:
π=C/d which can be rearranged to
C=πd
Since the diameter is equal to twice the radius of the circle, ie d=2r
C=2πr dividing both sides by 2π gives you:
r=C/(2π), the "spoke" in our problem is equal to the radius of a circle, and we are told that C=42in so:
r=42/(2π) in
r=21/π in
r≈6.68 in (to nearest hundredth of an inch)
It looks like this is a square pyramid net, and to find the surface area you need to know the base and height. By looking at the image 5 ft is the height and the base is 3 ft.
The surface area of the square pyramid is <u>40.32</u>
hope this helps!
The common ratio of the GP is 3/2.
Step-by-step explanation:
- Step 1: Find first and second terms to find the common ratio, r = a(2)/a(1)
⇒ a(1) = 3^1-1/2^1 = 3^0/2 = 1/2
⇒ a(2) = 3^2-1/2^2 = 3^1/4 = 3/4
- Step 2: Find the common ratio
⇒ r = a(2)/a(1) = 3/4 ÷ 1/2 = 3/4 × 2/1 = 3/2
