You use the Pythagorean theorem which is a^2+b^2=c^2
So....
.8^2+.6^2=c^2
.64+.36=c^2
1=c^2
1=c becaaue the square root of one is one
Answer:
47.856
Step-by-step explanation:
We will use
SOH
CAH
TOA
to solve this
we have the adjacent length, but need the hypotonouse
which means that we will use CAH
we have
cos(43)= 35/p
solve for p
47.856
the fraction in the image is 2 1/2
let's try each choice
1) 2/3 x 5/2 = 10/6 = 5/3
2) 5/4 x 5/2 = 25/8
3) 3/3 x 2 1/2 = 2 1/2
4) 4/5 x 5/2 = 20/10 = 2

Answer:
1,256.8in
Step-by-step explanation:
Given data
Height h =4in
Radius r= 5in
The expression for the volume of cylinder is
V=πr²h
Substitute
V=3.142*4²*5
V=3.142 *16*25
V=1,256.8in³
Joseph is going to pay full price for the higher priced book so we start with 15 dollars. Then he pays 50% of the second book which is 10 dollars, so we find 50% of 10 and then add it to 15...
15 + 50% x 10 =
15 + .5 x 10 =
15 + 5 = 20
He pays a total of $20
