Answer:
314 square inches
Step-by-step explanation:
The radius is half the diameter. If the diameter is 20 inches, the radius is 20/2 = 10 inches. The area is given by the formula ...
A = πr²
Filling in the given values, we get ...
A = 3.14×(10 in)² = 314 in² . . . . area of the circle
-2 - 1 = -3
The answer is -3.
Answer:
C: 40 degrees
Step-by-step explanation:
50+2y+y+10=180
60+3y=180
3y=120
y=40
t-1/3= 1/8
t-1/3+1/3= 1/8+1/3
t= 1/8+1/3
Find common denominator for the fractions.
common denominator is 24
Multiply by 3 for 1/8
Multiply by 8 for 1/3
t= 3/24+8/24
t= 11/24
Answer is t= 11/24
