Surface area is the area that is on the outside of a figure and will be used when you have to cover something, but a volume is an area inside an object and is used in finding the amount someone can hold within something else.
Answer: 1406.25
Step-by-step explanation:
The soccer field at a park is 9,000 square yards. The soccer field takes up 6 2/5 square inches on the map of the park. How many square yards does 1 square inch on the map represent? Show your work. Help me pls
Given that:
Area of soccer field = 9000 sq yards
Soccer field takes up 6 2/5 square inches on the map of park
Hence,
9000 yd² = 6 2/5 in²
Let 1 in² on map = m
9000 yd² = 32/5 in² - - - (1)
m = 1 in² - - - (2)
Cross multiply ;
6.4 * m = 9000
m = 9000/6.4
m = 1406.25
Hence,
1 in² on map = 1406.25 feet²
900
Answer:
10 tomato plants and
15 rose plants
Step-by-step explanation:
Let t be the no. of tomato plants,
And r the no. of rose plants
t + r = 25
t + 2r = 40
t = 25 - r
25 - r + 2r = 40
r = 15
t = 25 - 15
t = 10

Answer:
Pedro can fill 253.2527 cups from that bowl.
Step-by-step explanation:
In order to calculate how many cups pedro can fill we first need to calculate the volume of punch he had in the bowl. Since the bowl is half a sphere then we need to use the following formula:
volume of bowl = (volume of sphere)/2
volume of bowl = [(4/3)*pi*r³]/2
volume of bowl = [(4/3)*pi*(9)³]/2 = 1526.81 inches³
Now we need to calculate the volume of each cup, since it's a cone we have:
volume of cup = [pi*(r²)*h]/3 = [3.14*(1.2)²*4]/3 = 6.0288 inches³
The number of cups is given by:
cups = volume of bowl / volume of cup = 1526.81/6.0288 = 253.2527 cups
