Answer:
D. Secant is the reciprocal of cosine
Step-by-step explanation:
Secant is 1/cosine, so it is the reciprocal.
2783- The 2 is in the thousands place so the value is 2*1000= 2000
7283- Thw 2 is in the hundreds place so the value is 2*100= 200
2000/200=10
Final answer: The value of 2 in the number 2783 is 10 times the value of the 2 in the number 7283.
Answer:
180.6 cubic inches. (Nearest tenth is the same as 1 decimal place)
Step-by-step explanation:
The volume of a cylinder formula is:
V
=
π
r
2
h
The diameter is
10
inches, well half of the diameter is
5
inches which is the radius. Radius is half of the diameter.
If you want the diameter back, just double it.
5
+
5
=
10
.
So we can now plug the numbers into the formula.
V
=
π
(
5
2
)
(
2.3
)
V
=
π
(
25
)
(
2.3
)
(5 Squared =25)
V
=
57.5
π
But if you didn't want it in terms of
π
, so you multiply:
57.5
×
3.14
=180.55
but rounding that to the nearest tenth is the same as rounding to
1 decimal place so you get
180.6 cubic inches.
