Answer:
452.4 ft²
Step-by-step explanation:
The radius on the blueprint is (18 cm)/2 = 9 cm, so the actual radius will be ...
radius/(9 cm) = (4 ft)/(3 cm)
radius = (9 cm)(4 ft)/(3 cm) = 12 ft
Then the area of the fountain is ...
A = πr² = π(12 ft)² = 144π ft²
The area is about 452.4 ft².
Answer:
C
Step-by-step explanation:
By tracing the figure, we see that we go around a semicricle twice and go in a straight path twice. So the perimeter of this figure consists of two semicircles and two line segments, hence the answer is C.
Answer:
3.2%
Step-by-step explanation:
The computation of the annual rate of interest is shown below:
As we know that
Simple interest = Principal × rate of interest × time period
($1,857.60 - $1,800) = $1,800 × rate of interest × 1
$57.60 = $1,800 × rate of interest × 1
So, the rate of interest is
= $57.60 ÷ $1,800 × 100
= 3.2%
Hence, the rate of interest on annual basis is 3.2%
The value fo k is
. This is because c, the constant, is the y-intercept. The graph shows where the line intersects the y-axis, which is -3. So you substitute -3 with c. To find the value of k, plug in the coordinate with the x and y values and then solve for k.
