Answer:
78.5 cm^2
Step-by-step explanation:
1, find the radius (half a diameter) R = 5
3.14 * 5^2
3.14 * 25 = 78.5
Answer:
AC=BD
BY using the rules of parallelograms we see that since AB is l l to DC and AD is l l to BC, then the length of the diagonals BD and AC must be equal
Step-by-step explanation:
First, find the prime factorization of both numbers.
378/2 = 189
189/3 = 63
63/3 = 21
21/3 = 7
7/7 1
378 = 2 * 3^3 * 7
132/2 = 66
66/2 = 33
33/3 = 11
11/11 = 1
132 = 2^2 * 3 * 11
For the GCF, choose the common factors with lower exponent.
378 = 2 * 3^3 * 7
132 = 2^2 * 3 * 11
From 2 and 2^2 choose 2.
From 3 and 3^2 choose 3.
7 and 11 are not common, so do not choose them.
GCF = 2 * 3 = 6
Answer:
1cm³
Step-by-step explanation:
You do not need a calculator for this.
The formula for the volume of a rectangular prism is:
Length × Width × Height = Volume
If we substitute our numbers in:
5/4 × 4/3 × 3/5 = 1cm³
All you need to do is multiply across.
5 × 4 × 3 = 60
4 × 3 × 5 = 60
The numerator and denominator both equal 60. So the fraction would look like this if you were to keep it as a fraction.
60/60
