25 is 5 times as 5 so here is the answer
Answer:
Area = 72.62 m²
Step-by-step explanation:
Area of a triangle with the given three sides is given by,
Area =
Here, s =
And a, b, c are the sides of the triangle.
From the question,
a = 20 m, b = 10 m and c = 15 m
s =
s = 22.5
Substitute these values in the formula,
Area =
=
=
= 72.62 m²
Answer:
C
Step-by-step explanation:
The area of a circle is pi * r^2. The radius is 7 because the diameter is 14 so the radius is 14/2. The square of 7 is 49. Pi is approximately 3.14, so 49 * 3.14 is about 154.
117 is 25% of 468.
Explanation:
Simple way to find percentages, is make it into a fraction.
117/468, then divide 117 by 468.
Which is .25 or 25%
Hope this helps!
