I'm sorry I really don't know I'm not really good with math that's why I got them brainly for other people's help because I really not that cool math and I'm homeschooled
To get the area of a triangle you use the equation A=1/2bh so 1/2 x 7 x 8= 28 square meters.
Option D:
Surface area of the cylinder = 753.6 cm²
Solution:
<u>To find the surface area of the cylinder:</u>
Given data:
Radius of the cylinder = 6 cm
Height of the cylinder = 14 cm
The value of π = 3.14
Surface area of the cylinder = 
= 226.08 + 527.52
= 753.6 cm²
Surface area of the cylinder = 753.6 cm²
Option D is the correct answer.
0.185 is your decimal answer but your fraction answer is 37/200 according to my spidey senses.
Answer:
Step-by-step explanation:
erasers=e
pencils=p
3e+5p=7.55 ...(1)
6e+12p=17.40
divide by 2
3e+6p=8.70 ...(2)
(2)-(1) gives
p=8.70-7.55=1.15
from (1)
3e+5(1.15)=7.55
3e+5.75=7.55
3e=7.55-5.75
3e=1.80
e=1.80/3=0.60
cost of 1 eraser=$0.60
cost of 1 pencil =$1.15
