Formula: A=(pi)r^2
Substitution: A=3.14(7^2)
A=3.14(49)
Solve: A=153.86 in^2
*I personally like to use the pi sign on my calculator to multiply the radius squared by, but my keyboard did not have a pi sign. Usually, the pi sign is more exact. If you used the pi sign, your answer would be 153.94 inches^2. Hope this helps!
Answer:
A =39 ft^2
Step-by-step explanation:
The area of the triangle is given by
A = 1/2 bh where b is the base and h is the height
The base is 5+8 and the height is 6
A = 1/2(5+8) *6
A = 1/2 *13*6
A =39 ft^2
Answer:
6. c = 5
7. b = 8
8. a = 0.75
9. b = 12
10. c = 0.5
11. c = 17
12. b = 1.34
13. a = 4.5
14. a = 1.2
15. c = 6.1
16. b = 15
17. c = 41
18. a = 7
19. c = 8.5
20. b = 4
Step-by-step explanation:
You need to use Pythagorean theorem. Put the number for a in a, b in b, and c in c. DON'T forget to square a, b, and c.
Answer: Area = 836 feet²
Step-by-step explanation:
We will call L the length and W the width, then
L = 2W - 6 feet
L = 2 x 22 feet - 6 feet = 44 feet - 6 feet = 38 feet
Area of a rectangle is L x W
Area = 38 feet x 22 feet = 836 feet²
Answer : Area = 836 feet²
