take the area of each shape and add it up
Answer:
35/6
Step-by-step explanation:
add the fractions in parentheses by finding the common denominaters and adding. then multiply your answer by 5/6. :)
0.578 rounded to the nearest tenth would be 0.6, since the 7 in the hundredths spot is higher than 5.
Sector area = (central angle / 360) * PI * radius^2
sector area = (210 / 360) * PI * 2.3^2
sector area = (7 / 12) * PI * 5.29
