P=r x 2 x pi
= 3 x 2 x 3.14
= 6 x 3.14 = 18.84
I’m tired I’ve so much homework to complete and a long day of school :(
Answer:
1233cm^2
Step-by-step explanation:
a of triangle = 1/2 bh
1/2 x 12 x 9 = 54
108 x 2 = 108
a of regtangle = l x w
25 x 15 = 375
375 x 3 = 1125
total surface area = 1125 + 108 = 1233cm^2
Answer:
A and B
Step-by-step explanation:
9x+9+5x-6
14x+3
32x+8-18x-5
14x+3
5/8 9/x
Cross multiply
9x8=72
5×x=5x
Rewrite the equation
72 = 5x
Divide by 5
72÷5=14.4
So, x=14.4
