Answer:
perimeter= 17/3
area= 12
Step-by-step explanation:
for perimeter:
basically you need to add all sides
so to make it easier yo can put the equation in this way
4/3 + 5/3 + 8/3 = (and that gives you) 17/3
given they have common denominator you just add the numbers
for area:
the equation of the area of a triangle is:
1/2 x base x height
you just need to replace to end up with
1/2 x 8/3 x 6 = 12
Answer:
can u give better picture
(B) 16.5π
<u>Explanation:</u>
The shape given is a cylinder
The height, h of the cylinder = 4cm
Diameter of the cylinder = 3cm
Radius, r = 1.5 cm
Surface area of cylinder, A = ?
We know:
Surface area of cylinder = 2πrh + 2πr²

Therefore, the surface area would be 16.5π
Answer:
$20
Step-by-step explanation:
So since there are 4 three bagels in a dozen, and each three bagels are 5 dollars then you multiply 5 times 4.
You can also find how much it is for 1 bagel by divided 5 dollars by 3 bagels. Multiply that by 12.
Hope this helps! (^-^)
A^2 + 31 = 155 - I squared each of b and c for those numbers
a^2 = 155 - 31
a^2 = 124
a = 4 * sqrt(31)
