Answer:diameter=9.92m
Step-by-step explanation:
Area=77.28
π=3.14
Area=π x (d/2)^2
77.28=3.14 x (d/2)^2
Divide both sides by 3.14
77.28/3.14=(3.14x(d/2)^2)/3.14
24.6=(d/2)^2
Take them square root of both sides we get
d/2=√(24.6)
d/2=4.96
d=4.96 x 2
d=9.92
Answer:
B)48
Step-by-step explanation:
Cut the figure to get 2 rectangles. 9x4=36 And then 6x2=12. Add the two numbers 36+12 to get 48.
A, C, E
any mathematical expression that then includes an equal sign becomes a sentence or equation
To 3 significant figures:
19.3 cm
The formula to find it is 2(l x h + h x w + w x l) = SA in which l = length, h = height, and w = width.
Hope this helps!
