Answer:
B
Step-by-step explanation:
<h2>63.6 cm</h2><h2 />
Cut diameter in half to find radius
9/2 = 4.5
radius = 4.5
This is the formula for area of a circle:
pi * radius^2
pi * 4.5^2
20.25pi
Now find pi:
20.25 * pi = 63.6
Answer:
63.6 cm is the area

Answer:
45 3/10 miles per hour
Step-by-step explanation:
Distance travelled by the car = 30 1/5 miles
Time taken = 2/3 of an hour
Average speed = distance travelled / time taken
= 30 1/5 miles ÷ 2/3 of an hour
= 151/5 ÷ 2/3
= 151/5 × 3/2
= (151 * 3) / (5 * 2)
= 453 / 10
= 45 3/10 miles per hour
Average speed = 45 3/10 miles per hour
