Answer:
Step-by-step explanation:
For pi i use the estimate 3.14
First find the radius of the sphere using the formula circumference= pi * diameter 
then divide both sides of the equation by d to get the diameter, which is about 86.94.
To get the radius, divide the diameter by 2, which equals 43.47.
Use the formula 
to get the surface area, which is, rounded to the nearest number, is 23,734 feet
Answer:
6.15 kilograms of pears
Step-by-step explanation:
The total is 8.2 kilograms. Since 1/4 of the weight is apples, we know that 3/4 of the weight is pears. So we multiply 8.2*0.75.
8.2*0.75=6.15
Therefore, the farmer sold 6.15 kilograms of pears at the farmer's market.
Answer:
13
Step-by-step explanation:
the difference is -5
- nth=a+(n-1)d
- a=253,n=49,d=5
- 253+(49-1)×-5
- 253+48×-5
- 253+(-240)
- 253-240=13
the 49th term is 13
