The shape is composed of three squares and two semicircles.Select all the expressions that correctly calculate the perimeter of
lidiya [134]

Answer:

100+20π

Step-by-step explanation:

Find the diagram attached.

Perimeter of a square =4L

L is the side length of a square

From the diagram;

L = 10

Perimeter of a square = 4(10) = 40

Perimeter of 3 squares = 3(40) = 120

2 semi circle = a circle

Perimeter of a circle= 2πr

radius of the Circle = length of a side of the square.

Area of the circle = 2π(10)= 20π

Perimeter of the shape = Perimeter of the two semicircle + area of the 4squares = 100+20π

Find the volume of a cylinder with a radius of 6cm and height 15cm? (To the nearest whole centimeter)
mr Goodwill [35]

For this case, we have that by definition, the volume of a cylinder is given by:

V = \pi * r ^ 2 * h

Where:

A: It's the radio

h: The height of the cylinder

We have the values:

r = 6 \ cm\\h = 15 \ cm

Substituting:

V = \pi * (6 ^ 2) * 15\\V = \pi * 36 * 15\\V = 1696.46 \ cm ^ 3

Answer:

V = 1696.46 \ cm ^ 3

Stephanie has $42,750 in student loans at a 6% compound interest
jek_recluse [69]

Answer:

You first take the annual interest rate on your loan and divide it by 365 to determine the amount of interest that accrues on a daily basis. Say you owe $10,000 on a loan with 5% annual interest. You'd divide that rate by 365 (0.05 ÷ 365) to arrive at a daily interest rate of 0.000137.
