Answer:
26
Step-by-step explanation:
Area of a triangle is:
A = 1/2 b h
Given b = 13 and h = 4:
A = 1/2 (13 cm) (4 cm)
A = 26 cm²
Compare the areas of the 2 different pieces of paper.
For the circle, the area is A=pi * r^2, which works out to A = pi(5 inches)^2.
For the square, the area is A = s^2, where is the side length, which here is 11 inches.
Finish these calculations, and then compare your two areas. Which is the larger?
8/10. If you simplify it, it will be 4/5
hope this helps.
3a.
Explanation:
the mean, first of all, is the average. so, you need to find the average between 2 ans 4 since it has the same label. 2+4=6. 6/2=3
