Answer:
C = 21.98 ft^2
A = 38.465 ft^2
Step-by-step explanation:
The diameter is 7 ft
The radius is 1/2 of the diameter so 1/2 *7 = 3.5 ft
Circumference = pi*d
C =pi* 7
C =3.14 *7
= 21.98 ft^2
A = pi*r^2
= 3.14 (3.5)^2
= 3.14 (12.25)
= 38.465 ft^2
Answer:
No solution
Step-by-step explanation:
No solution.
You could graph y = |x| and then graph y = -5. You'd see quickly that these two graphs never intersect.
The absolute value function y = |x| can only be zero (0) or positive.
Well how many students are there in the class??<span />
Answer:
area = 132 cm²
Step-by-step explanation:
area of rectangle = 7 x 12 = 84
area of one triangle = 8 x 6 x 0.5 = 24
total area = 84 + 24 + 24 = 132 cm²
