Answer:
Step-by-step explanation:
Area of a triangle is A = height x base / 2
So plug in what you know.
42 = (14 x b)/2 get rid of the 2 by multiplying both sides by 2 which gives:
84 = 14 x b get rid of the 14 by dividing both sides by 14
b = 84/14
b=6 cm
Answer:
The diameter is: d = 5m
Step-by-step explanation:
We know that
Circumference of Circle = 2πr
Given that
The circumference of a circle = 5π
so the equation becomes
Circumference of Circle = 2πr
5π = 2πr
2πr = 5π
r = 5π/2π
r = 5/2 m
As we know that:
The diameter is twice the radius. i.e. d = 2r
Thus, the diameter is:
d = 2(5/2)
= 5 m
Therefore, the diameter is: d = 5m
