Answer:
A
Step-by-step explanation:
The base is the circle.
To find the area of the circle, use pi*r^2
pi = 3.14
r = 6
- Area = 3.14 * 6^2
- Area = 3.14 * 36
- Area = 113.04
Answer:
A = 307.9 sq/cm
Step-by-step explanation:
Find the radius of the semi-circle
diameter + half the circumference = 72 cm
2r + pi*r = 72
r(2+pi) = 72
r = 72%2F%28%282%2Bpi%29%29
r = 14
:
what will be the area of that semicircle?
A =1%2F2*pi%2A14%5E2
A = 307.9 sq/cm

Answer:
13x² - 4x
Step-by-step explanation:
3x + 4x² - 7x + 9x² ← collect like terms
= (4x² + 9x² ) + (3x - 7x)
= 13x² + (- 4x)
= 13x² - 4x
