Sliva [168]
Hello!

To find the volume of a rectangular prism you use the equation

V = lhw

v is volume
l is length
h is height
w is width

Put in the values you know

180 = 6 * 5 * w

Divide both sides by 6

30 = 5 * w

Divide both sides by 5

6 = w

Answer is 6cm

Hope this helps!

Question 6 options: What is the approximate area of a circle with a diameter of 56 cm? Use your calculator button for π. Round y
Andrew [12]

The area of circle is 2463.0086 cm².

Step-by-step explanation:

Given,

Diameter of circle = 56 cm

Radius of circle = \frac{Diameter}{2}

Radius of circle = \frac{56}{2}=28\ cm

We know that;

Area of circle = \pi r^2

Area of circle = \pi *(28)^2

Area of circle = π * 784

Area of circle = 2463.00864041 cm²

Rounding off to four decimal places

Area of circle = 2463.0086 cm²

The area of circle is 2463.0086 cm².
