Answer:
180 cm³
Step-by-step explanation:
A glass is 1/3 full. Then 75cm³ of orange juice is poured in. The glass is now 3/4 full. What is the total volume of the glass?
Let
x = total volume of the glass
1/3x + 75 = 3/4x
75 = 3/4x - 1/3x
75 = 9x-4x/12
75 = 5/12x
x = 75 ÷ 5/12
x = 75 × 12/5
= 900/5
= 180 cm³
x = 180 cm³
Answer: Diameter: 8
Area: 201.1
Step-by-step explanation:
Diameter: Use the formula for the area of a circle:
Use the formula for the area of a circle:
A=πr2
Here, the area is 16π:
16π=πr^2
Divide both sides by π:
16=r^2
Take the square root of both sides: √16=√r^2
4=r
Since the radius of the circle is 4, the diameter is twice that:
d=4×2=8
Area:
Formula:
A = π r^2
A= Area R= Radius
Add Radius
A= π 8^2
Solve:
Simplify π⋅8^2
Exact Form:
A=64π
Decimal Form:
A=201.06192982
Gina saw 25 monkeys
25 ÷ 5 = 5
5 + 7 = 12
12 + 6 = 18
25 + 5 +12 + 6 = 48 animals
gina saw 48 animals at the zoo
