Answer:
63.62
Step-by-step explanation: A=πr^2=π·4.52≈63.61725
81 because 81 is a perfect square and 27 times 3 =81
A = π · r²
r = 6 cm
A = π · (6 cm)² = 36π cm² ← the end answer
Answer:
I = $ 220.00
Step-by-step explanation:
I = $ 220.00
Equation:
I = Prt
Solve:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 2200 × 0.05 × 2 = 220
I = $ 220.00
The simple interest accumulated
on a principal of $ 2,200.00
at a rate of 5% per year
for 2 years is $ 220.00.
