Answer:
The area of the circle is 379.94 mm²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 11 mm
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (11 mm)²
a = 3.14 * 121 mm²
a = 379.94 mm²
Round to the nearest tenth
a = 379.94 mm² = 379.9 mm²
The area of the circle is 379.9 mm²
Answer:
step 3
Step-by-step explanation:
3 x 8 = 24 thats correct but 5 x 5 = 25 not 5
i took the test
Answer:
I think the first mistake was made in step 1
y = a(1 + r)ˣ
a = 15 "<em>initial" means what you started with on the first day</em>
r = 6 <em>the rate it increased is the slope (
</em>
y = 15(1 + 6)ˣ
Answer: y = 15(7)ˣ
It is 16,000. because 0 is lower than 5
