Answer:
3.8 meters
Step-by-step explanation:
In order to find the circumference for a circle, we use the formula π(radius)²
The circumference give is 45.84 and the π given is 3.14
All we have to do is to just substitute them.
45.84 = 3.14(radius)²
45.84 / 3.14 = radius²
14.6 = radius²
radius = √14.6
radius = 3.82 ≅ 3.8
Answer:
Step-by-step explanation:
81
=
3
4
and
27
=
3
3
, so this equation can also be written as
3
4
x
=
3
3
(
x
+
2
)
=
3
3
x
+
6
.
Since the bases are now the same, we can equate exponents to get
4
x
=
3
x
+
6
so that
x
=
6
(technically this equating of exponents requires the fact that exponential functions (with base not equal to 1) are one-to-one functions).
