AysviL [449]

2)The circumference or perimeter of a circle with radius $r$ is

$P=2\pi r$ . Given $P=28\pi$ . Therefore,

$2\pi r =28\pi \\ r=14\\ d=2r=28\\ A=\pi r^2 \\ A=\pi (14)^2\\ A=[tex] 196\pi$

Thus the radius is $14\;ft$ , diameter $28\;ft$ and area $196\pi \;ft^2$

pentagon [3]

Answer:

14 in^3.

Step-by-step explanation:

The volume = volume of the bottom prism + volume of the top pyramid

= area of base * height of the prism + 1/3 * area of base * height of the pyramid

= 2 * 1.5 * 4 + 1/3 * (2*1.5) * 2

= 3*4 + 1/3 * 6

= 14 in^3.

Given log5 3=0.6826 and log5 8=1.2920, evaluate the expressions Please help!?

gulaghasi [49]

Answer:

a) 1.3652

b) 1.3906

Step-by-step explanation:

a) log5 9 = log5 3² = 2log5 3 = 2(0.6826) = 1.3652

b) log5 75/8 = log5 75 - log5 8 = log5 3×25 - log5 8=

log5 3 + log5 5² - log5 8 = 0.6826 + 2 - 1.2920 = 0.6826 + 0.708 = 1.3906
