The diameter of a baseball is about 1.4 in.

1 answer:

3 0

You need to find the surface area and the volume. The formula for surface area is 4*3.14(pi)*radius^2 which is equal to 6.5144 inches^2 in this case. The amount of rubber needed to fill it is equal to the volume. The formula for volume of a sphere is 4/3*3.14(pi)*radius^3, just plug in the number (remember radius is half of diameter) and that will give you the answer!

What is the answer?

Answer:

1:200

5.6 cm^2 : y (as actual area)

y = 200 mutifly 5.6 cm^2

y= 1120 cm^2

We know 1m =100cm

so, 1m^2 =100cm x 100 cm = 1000cm^2

y= 1120 m^2/ 100x100

= 0.112 m^2

Can someone help me with this

Dimas [21]

Answer:

596.0 ft

Step-by-step explanation:

The relationship between the two legs of a right triangle and an acute angle is ...

Tan = Opposite/Adjacent

The height (h) of the lighthouse is the side opposite the angles of elevation. If d is the distance between A and B, we can write two tangent relations:

tan(14°) = h/770

tan(8°) = h/(770 +d)

Equating expressions for h gives ...

770·tan(14°) = (770 +d)·tan(8°)

770(tan(14°) -tan(8°)) = d·tan(8°) . . . . subtract 770·tan(8°)

d = 770·(tan(14°)/tan(8°) -1) . . . . . divide by the coefficient of d

d ≈ 770·(1.7740609 -1) = 596.03

The distance from point A to point B is about 596.0 feet.

The area of a square piece of cardboard is 81 square inches. What is the length of the cardboard? A. 10 inches B. 9 inches C. 8

Vadim26 [7]

The answer is B. 9 inches because a square has 4 equal sides. The area of a square equals length times width...

So that means all 4 sides are 9 inches

9x9=81

The city purchased 24 new buses that each hold 32 passengers. It also purchased 18 new smaller buses that each hold 27 passenger

FrozenT [24]

You would multiply 24 and 32. Then multiply 18 and 27. Would add both answers together. That should 768+486= 1254 people. The total people is 1254.
