Answer:
Option B.
Step-by-step explanation:
step 1
Find the central angle of the shaded sector
Remember that the diameter divide the circle into two equal parts ( 180 degrees each part)
so
Let
x -----> the measure of the central angle of the shaded sector
∠x+72°=180°
∠x=180°-72°=108°
step 2
Find the area of the circle
The area of the circle is
we have
assume
substitute
step 3
Find the area of the shaded sector
Remember that the area of the complete circle subtends a central angle of 360 degrees
so
by proportion find the area of a sector by a central angle of 108 degrees
Choose the most appropriate unit to measure the weight of each.
Write oz., lb., or T.
#1. Car = T
#2. Computer = lb.
#3. Bowling Ball = lb.
#4. Onion = oz.
#5. Tyrannosaurus Rex = T.
#6. Vacuum Cleaner = lb.
#7. Q. A hippo weighs about 5,000 lb.. Does the same hippo weigh more or less than 5,000 oz.?
A. If one ounces is 0.0625 pounds then 5000 ounces are 312.5 pounds so the same hippo weighs more than 5,000 oz.

Answer:
14.8 kg
Step-by-step explanation:
Density = Mass / Volume
9.86 g/cm3 = Mass / 150 cm3
Mass = 9.86 x 150 = 1479 g
