225 serves because you need to set up a proportion. The proportion is 2/5=90/x then solve for x by cross multiplying, which gives you 450=2x. Then divide 450 by 2 which gives you 225. Work shown in the attached picture.
The broadest group is Domain which consists of Eukarya which includes the organisms that most people are most familiar with-all animals, plants, fungi, and protists. They also include the vast majority of the organisms that paleontologists work with.
Answer:
= 1099 cm^2
Step-by-step explanation:
The surface area of a cylinder is found by using the formula
SA=2πrh+2πr^2
We know the diameter. To find the radius, we take the diameter and divide by 2.
r =d/2
r =14 cm/2 = 7 cm
h = 18 cm
Substituting what we know
SA = 2 * pi * 18 * 7 + 2 * pi * (7)^2
= 252 *pi + 2* pi *49
= 252 pi + 98 pi
= 350 * pi
Let pi be approximated by 3.14
SA = 350 * 3.14
= 1099 cm^2
1 It's the only positive number whose reciprocal is its equal
