Answer:
The area of the circle is 615.44ft²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 14ft
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (14ft)²
a = 3.14 * 196ft²
a = 615.44ft²
The area of the circle is 615.44ft²
Answer:
About 121.25
Step-by-step explanation:
<em>Step 1: Interpret x and y</em>
y is the number of accidents that occur = ?
x is the speed = 60 km/h
<em>Step 2: Substitute value of x in the equation</em>
y=0.0875x² - 10.5x + 436.25
y=0.0875(60)² - `10.5(60) + 436.25
<em>Step 3: Find the value of y</em>
y=0.0875(60)² - `10.5(60) + 436.25
y = 121.25
Therefore, the right answer is the last option which is 'about 121.25.'

Sample size, N = 3450
Point estimate of republican, p = 1789/3450 = 0.5186 = 51.86%
Z = 1.96 at 95% confidence level
Now,
True percentage of republican residing in California = p +/- Z*Sqrt [p91-p)/N] = 0.5186+/- 1.96* Sqrt [0.5186(1-0.5186)/3450] = 0.5186+/-0.017 = (0.5016,0.5356) = (50.16%,53.56%).
Answer:
282.4
Step-by-step explanation:
V=1/3 pi Bh where B is the area of the base and h is the height
V=1/3 (3.14159)(10.6)^2(2.4)=282.4
Please forgive me if this answers wrong but I think your answer will be 54, -6, 24
