Answer:
14 kilometers
Step-by-step explanation:
This is really about calculating perimeter.
So we need the lengths of all the sides of this right triangle.
Notice all the legs are 4 units or 4 kilometers
the hypotenuse is 4*root(2) because this is a 45-45-90 triangle.
so
Perimeter = 4 + 4 + 4
let us add: P = 4 + 4 + 4root(2) = 13.656854 km.
the nearest kilometer is 14 km.
Answer:
we have centre of circle as (30,40) and radius = 1
Step-by-step explanation:
Given that a car is moving on a circle on a plane.
At time t (seconds),
and
when we square and add both the equations we get
(since sin square + cos square = 1 always)
i.e. we have centre of circle as (30,40) and radius = 1

Answer:
505.4 in²
Step-by-step explanation:
½d2= 19×tan 35° = 19×0.7 = 13.3 in
d2 = 2×13.3 = 26.6 in
d1 = 2×19=38 in
the area of Rhombus =
½×38×26.6 = 505.4 in²
Radius = Diameter ÷ 2
Radius = 10 ÷ 2 = 5
.
Volume = πr²h
Volume = π(5)² (20) = 500π cm³
.
Answer: 500π cm³
