Answer:
8,00,000
Step-by-step explanation:
Formula for the area of a circle:
A = πr² (A = Area π(pi) r = radius)
You know:
r = 14 inches So substitute/plug it into the equation
[Radius is (half) of the diameter. The diameter is 28, so half of 28 = 14]
A = πr² Plug in 14 into "r" since r = 14
A = π(14)² Find 14² --> 14 x 14 = 196
A = 196π in² Your answer is the 4th option

Answer:
A. 14.2 in.
Step-by-step explanation:
Perimeter = 3.7 + 3.6 + 3.4 + 1.9 + g
Let's find g.
a = 1.9 in. (Tangents drawn from an external point of a circle are congruent)
b = 3.4 - 1.9 = 1.5 in.
b = c = 1.5 in. (Tangents drawn from an external point)
d = 3.6 - 1.5 = 2.1 in.
d = e = 2.1 in. (Tangents drawn from an external point)
f = 3.7 - 2.1 = 1.6 in.
f = g = 1.6 in. (Tangents drawn from an external point)
✔️Therefore,
Perimeter = 3.7 + 3.6 + 3.4 + 1.9 + 1.6 = 14.2 in.
Answer:
10,000 :)
Step-by-step explanation:
5,089 rounded =5,000
4,722 rounded= 5,000
= 10,000
6 x -9 = -54
<span>6 + (-9) = -3
</span>x2<span> - 3x - 54 = 0
