Half of 126 is 63 because 63+63=126 and 126/2=63
The upside down t means that the two lines are perpendicular
Answer:
Step-by-step explanation:
surface area of cylinder=2πrh
SA=1/2×2×π×3×25+2 ×(1/2×π×3²)=75π+9π=84π≈84×3.14≈263.76 cm²
if lowerside is also counted then area of lower side=25×6=150
total surface area=263.76+150=413.76 cm²
if we take π=22/7
84 π=84×22/7=12×22=264 cm²
if base is also counted then area=264+150=414 cm²
The length of BC is also 6 because the rhombus is equilateral or congruent sides meaning each side are equal to eachother
Answer:
Area: 42 cm²
Perimeter: 28.4 cm
Step-by-step explanation:
Simply plug in 4.2 cm for x into x + 5.8 to find the width. You width should be 10.
Area: Multiply 10 by 4.2 and you should get 42
Perimeter: Add up all the sides together (4.2 x 2 + 10 x 2) and you should get 28.4
