Answer: Down there there is an image with the correct answer and step by step
I hope that it helps you!
Area=pi times radiius^2
radius=diameter/2
diamter=5
radius=5/2=2.5
pi=3.14 aprox
area=3.14 times 2.5^2
area=3.14 times 6.25
area=19.625 ft^2
round
19.6 round up
20
the answer is 20 ft^2
Answer:
-19
Step-by-step explanation:
1) substitute a with 2 and b with 5
(3 + 2)^2 * (4-5) + √36
2) solve the brackets and the square root
(5^2) * (-1) + 6
3) solve the power
25 *(-1) + 6
4) solve the multiplication
-25 + 6
5) solve the sum
- 19
