Answer:

3.14 square units

Step-by-step explanation:

Circumference of a circle = 2πr

2πr = 6.28

r = 6.28/2π

r = 3.142/π

Area of a circle = πr^2

slot in the value of r

Area of the circle = π( 3.142/π)^2

" = π(9.87/ π^2)

" = 9.87/π

π = 3.14

Area of a circle = 9.867/ (3.14)

" = 3.14 square units

Find the area pf a trapezoid with a base of 26.7 ft , a height of 15.4 and top of 9.9 ft

evablogger [386]

Hello!

To find the area of the trapezoid, you use the formula A=1/2h(a+b), where a and b represent the two base lengths.

Since we already know the two bases and the height, we can just plug them into the equation to find the area.

A=1/2·15.4(26.7+9.9)
A=1/2·15.4(36.6)
A=1/2·563.64
A=281.82

The area is 281.82 ft².

I hope this helps!

As a 42.4 foot long pipe comes off the manufacturing line it is cut into 0.80 foot long sections. How many smaller sections are

Ludmilka [50]

53 smaller sections are created from the larger pipe

Step-by-step explanation:

The number of smaller section will be obtained by dividing the length of long pipe by the length of small section.

Given

Length of long pipe= 42.4 feet

Length of small section = 0.80 foot

$Total\ number\ of\ sections=\frac{Length\ of\ large\ pipe}{length\ of\ one\ small\ section}\\=\frac{42.4}{0.80}\\=53$

53 smaller sections are created from the larger pipe
