I’m having a lot of trouble, can someone guide me, step by step?
shutvik [7]

Answer:

Hi hopefully this helps you!

Step-by-step explanation:

To find the area of a circle you can use the formula A = πr^2

The radius of a circle is just the diameter divided by 2. In this case we know the diameter is 3, so the radius is 1.5

A = π(1.5)^2

   = 7.07

Because this is a semicircle, divide this area by 2

   = 3.53429 in^2

Add up the area of this semi circle with the area of the rectangle

A = (3.53429) + (3x4)

   = 15.53429 in^2

To find the circumference/ perimeter of a circle use this formula C = 2πR

C = 2π(1.5)

   = 9.42478 inches

Again because this is a semicircle, divide by 2

   = 9.42478 / 2

   = 4.71239 inches

To find the perimeter of this entire shape add up the circumference of the semicircle and the rectangle's sides and bottom

P = 4.71239 + 4 + 4 + 3

  = 15.71239 inches

So the final answer would be

A = 15.53 squared inches

P = 15.71 inches

Hope this helps! Best of luck in your studies <3

2.What is the solution of the solution of the equation 5^3x=15? Round to the nearest ten thousandth.
sveta [45]
Hmm
remember
a^c=b can translate to log_a(b)=c
so

5^{3x}=15 can translate to log_5(15)=3x
divide both sides by 3
(1/3)log_5(15)=x
log_5(15^{1/3})=x
use calculator, if you can't use change of base formula to do it
log_a(b)= \frac{log_c(b)}{log_c(a)} so
log_5(10^{1/3})= \frac{log_{10}(15^{1/3})}{log_{10}(5)}=x
evaluate using base 10 on your calculator
0.560869=x
