Answer:
<h2>132.25π m²</h2>
Step-by-step explanation:
The circumference of a circle is 23π
On the other hand, The circumference of a circle = 2×π×r ; where r is the radius.
then
by equating the last two expressions we get: 23π = 2πr then r = 23/2
then
the area = π × r² = (23/2)²×π = (132.25)×π
Answer:
Step-by-step explanation:
In order to calculate the volume of a triangular prism you need 2 things:
The triangles area and the prism's height.
Any prism's volume can be calculated by multiplying its base area with its height.
The Area of a triangle can be calculated in different ways.
The most used and "normal" way is:
(width * height) / 2
Another way is by using herons formula, which looks like this:
a, b, c = different sides of the triangle (length)
s = (a + b + c) / 2
a =
When you have the prism's base area () you just have to multiply:
(V = volume)

Answer:
8. the length is 88/5cm or 17.6cm
Step-by-step explanation:
8.perimeter =2L + 2W
when you convert the width 42/5 = 8.4
so 52 = 2L + 2*8.4
52= 2L + 16.8
52 - 16.8 = 2L
35.2 = 2L
divide both sides by 2
L = 17.6cm

Answer:
It is required to draw a number line showing equivalent fractions.
'Equivalent fractions' are the fractions having same value even though the digits involved are different'.
For example: Consider, and .
Now, we have,
= 0.5
= 0.5
Thus, the both fractions have the same value, even though we are dividing different digits.
Thus, and are called equivalent fractions.
So, we plot them on the number line, resulting in the following figure with point P = 0.5.
