You are told that the angle the shape makes is 90 hence its a quarter of the circle so you just find the area of the full circle and divide by 4
(6^2*pi)/4
36pi/4
9pi which is around 27 2 Sig fig
Answer:
B
Step-by-step explanation:
First of all
- Side opposite to Angle A = BC
- Side opposite to Angle B = AC
- Side opposite to Angle C = AB
We also know that smallest side is opposite the smallest angle and largest side is opposite the largest angle. The remaining side opposite of remaining angle.
It is given
A = 80
B = 30
C = 70
So, largest angle is Angle A and opposite side is BC
2nd largest angle is Angle C and opposite side is AB
smallest angle is Angle B and opposite side is AC
So, sides Largest - Smallest is:
BC, AB, AC
That is option B
Step-by-step explanation:
you put the values in place of the variable names and calculate.
y² + x + y
(-4)² + -3 + -4 = 16 - 3 - 4 = 16 - 7 = 9
Answer:
Actual distance is 4500 cm (45 m).
Step-by-step explanation:
A scale is a representative fraction that can be used to either increase or decrease proportionally the dimension of a given object.
scale =
It is in the form of a ratio.
From the question, Distance on map = 4.5 cm,
scale = 1 : 1000
=
scale =
Let the actual distance be represented by d.
So that,
=
⇒ d = 4.5 x 1000
= 4500
d = 4500
The actual distance is 4500 cm (45 m).
