Answer: 16 5/8
Step-by-step explanation:
3 1/2 = 7/2
4 3/4 = 19/4
7/2 * 19/4 = 133/8 or 16 5/8
Answer:
Cylinder Surface Area = (2 • π • r²) + (2 • π • r • height)
Surface Area = (2 * PI * 7^2) + (2*PI*7*22)
Surface Area = 307.8760800518 + 967.6105373057
Surface Area = 1,275.4866173575 Square Inches
Cylinder Volume = π • r² • height
Volume = PI * 7^2 * 22
Volume = 3,386.6368805698 Cubic Inches
Surface Area to Volume = 1,275.4866173575 / 3,386.6368805698 =
0.3766233766

Step-by-step explanation:
The equation of a circle is:
(x-h)2 + (y-k)2 = r2
where (h,k) is the location of the center and r is the radius. So we need to find h, k, and r. The center is given as (5,-4) so h = 5 and k = -4:
(x-5)2 + (y-(-4))2 = r2
(x-5)2 + (y+4)2 = r2
So we need to find r. Use the distance formula to find the distance between (5,-4) and (-3,2):
r = [(5-(-3))2+((-4)-2)2]1/2
r = [82 + (-6)2]1/2
r = [64 + 36]1/2
r = 1001/2
r= 10
The final equation is:
(x-5)2 + (y+4)2 = 102
Answer:
C. $314.44
Step-by-step explanation:
$390 x 0.25 Discount = $97.5
$97.5 x 1.075 Sales Tax = $104.81 <---this is how much you save
$390 - $104.81 = $314.44 Total Price
Savings: $104.81
Tax: $21.94
Total Payment: $314.44
If area of a circle can be expressed by the formula A=πr², where r is the radius of a circle. then √A/π is the radius in terms of the area of the circle.
<h3>What is Circle?</h3>
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given,
The area of a circle can be expressed by the formula A=πr²
r is the radius of a circle
We need to find the radius in terms of the area of the circle
A=πr²
Divide both sides by π.
A/π=r²
Now take square root on both the sides
√A/π=r
Hence, √A/π is the radius in terms of the area of the circle.
