Answer:
Rhian did better in the Math test.
Step-by-step explanation:
Given: Rhian scored out of
in a Math test. In the English test she scored
out of
.
To find: In which test did she do better?
Solution:
We have,
Rhian scored out of
in a Math test.
Rhian scored out of
in an English test.
So, first we need to find the percentage of the marks scored.
Percentage in the Math test .
Percentage in the English test .
Clearly, the percentage in the Math test is greater than the percentage in the English test.
So, Rhian did better in the Math test.
A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)
-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared
so when you plug the numbers in the formula it is
A = 3.14 x 6^2(squared)
A = 3.14 x 36
A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)
-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared
