Step-by-step explanation:
step 1. the area of a circle is A. A = (pi)r^2.
step 2. if the diameter is 8 cm then the radius is 4 cm.
step 3. A = (pi)4^2
step 4. A = 16(pi) = 50.24 cm.
Answer:
u= -4
Step-by-step explanation:
-36=9u
u=-36/9
u=-12/3
u=-4
(92+73+87+91)/4=x
92+73+87+91=343
343/4=86%
The average of the student’s grade is 86%
