Answer:
Area= 615 ft²
Step-by-step explanation:
Apply the formula for area of a circle to find the area watered when a sprinkler covers a full circle
Area of a circle= 
r= 14ft
Area= 3.14 × 14²
Area=615.44 ft²
Area= 615 ft²
Answer:
a=15
Step-by-step explanation:
You'll have <span>$634.87 after 6 years at 4% compounded quarterly, thus B:
You'll have </span><span>$3,619.80 after 6 months at 6.75% compounded monthly, thus A:
</span>Formulas where n = 1 (compounded once per period or unit t)
1. Calculate Accrued Amount (Principal + Interest) A = P(1 + r)^t
2. Calculate Principal Amount, solve for P. P = A / (1 + r)^t
4. Calculate the rate of interest in decimal, solve for r. r = (A/P)1/(^t - 1)
5. Calculate rate of interest in percent. ...Calculate time, solve for t.
