Daniel is blowing up a beach ball in the shape of a sphere. The package says that the ball has a diameter of 9 inches. Which measurement is closest to the volume of the beach ball when it is completely filled with air?

A. 84.8 cubic inches

B. 381.7 cubic inches

C. 972 cubic inches

D. 3,053.6 cubic inches

Answers

Answer:

B. 381.7

Step-by-step explanation:

because the diameter is 9 we know the radius is 4.5 (radius is half of the diameter)

the formula for volume: V= 4/3πr^3

V=4/3•π•4.5^3

that equals approx. 381.7

Measure the dimensions of the parallelogram shown to the nearest ½ centimeter.
Which measurement is closest to the area of the parallelogram in square centimeters?
Choices:
40 cm²
45.5 cm²
34 cm²
56 cm²

Answers

ok Kirishima

Answer:

The height of the triangle is 6.5cm

Step-by-step explanation:

First of all we need to use the formula to calculate the area of a triangle:

a = area = 45.5 cm²

b = base = 14 cm

h = height

a = (b * h) / 2

we replace with the known values

45.5cm² = (14cm * h) / 2

45.5cm² * 2 = 14cm * h

91cm² / 14cm = h

6.5cm = h

The height of the triangle is 6.5cm

Answer:

40 cm I think
