4*4 + 3.14*4*4/4 =28.56

Answer is A
Luda [366]3 years ago

Answer:

28.6 m²

Step-by-step explanation:

The measurements of the square are 4 by 4; this gives us an area of

4(4) = 16 m²

The quarter circle has a radius of 4 m.  The area of a circle is given by

A = πr².

Since we have a quarter circle, we multiply this by 1/4:

A = 1/4πr²

Using 3.14 for π and 4 for r,

A = 1/4(3.14)(4²) = 1/4(3.14)(16) = 3.14(4) = 12.56 m²

Together this gives us a total area of 16+12.56 = 28.56 m².

This rounds to 28.6 m².

Sadiq measured the dimensions of a 1 kg bag of sugar and found the length was 9.2 cm, the width was 6 cm and the height was 14.1
garik1379 [7]

Answer:

d=1.28\times 10^{-6}\ g/cm^3

Step-by-step explanation:

The mass of a bag of sugar, m = 1 kg = 0.001 g

Length of bag, l = 9.2 cm

Width of bag, b = 6 cm

Height of the bag, h = 14.1 cm

We need to find the density of the sugar bag.

Density = mass/volume

So,

d=\dfrac{0.001\ g}{9.2\times 6\times 14.1\ cm^3}\\\\d=1.28\times 10^{-6}\ g/cm^3

So, the density of the bag is 1.28\times 10^{-6}\ g/cm^3.
