Find the area of the figure to the nearest square unit.
alex41 [277]

Answer:

357 mi²

Step-by-step explanation:

The shape is made of a triangle and a half-square

we will calculate the area of each one

  • The half square:

let A1 be the area of the half-circle:

A1= (10²*π)/2 = 50π mi²

  • The rectangle:

Let A2 be the area of the triangle:

A2= 10*20=200 mi²

  • The whole shape:

let At be the total area:

At =A1+A2= 200+50π =357.07≈ 357 mi²

What is the distance from the right center field fence to third base? Show all of your work and round
Karolina [17]

Answer:

381.5\,\,\,ft

Step-by-step explanation:

Given:  Figure

To find: distance from the right center field fence to third base

Solution:

In a right angled triangle,

using Pythagoras theorem, square of hypotenuse is equal to sum of squares of base and perpendicular.

In ΔBAC,

BC^2=AB^2+AC^2\\(392)^2=x^2+(90)^2\\153664=x^2+8100\\153664-8100=x^2\\145564=x^2\\\sqrt{145564}=x\\381.5\,\,\,ft=x

So,

distance from the right center field fence to third base is 381.5 foot.

Samantha bought a refrigerator that is 3 1/2 feet wide, 5 1/2 feet tall, and 2 1/2 feet deep. How much space will the new refrig
Basile [38]

Answer:

48.125 ft³

Step-by-step explanation:

The space occupied by the new generator is the product of it's dimension:

The space occupied = Length * width * height

Space occupied = 3 1/2 * 5 1/2 * 2 1/2

Space occupied = 7/2 * 11/2 * 5/2

Space occupied = (7*11*5) / (2*2*2) = 385 / 8

Space occupied = 48.125 ft³
