Answer:
The answer is 13
Step-by-step explanation:
91 / 7 = 13
12 pi. So the equation for area is pi(r)squared so you have to set pi(r)squared equal to 36 and solve for "r". R is equal to six. After, you use "r" in the circumference formula which is 2(pi)r which would be 2(pi)6 which equals to 12pi
The area for this is
A= 7x9/2+3x9+9x6
= 31.5+27+54
= 112.5
Answer:
y = 4
Step-by-step explanation:
First we want to raise -1 to the power of 2
y = 2 * 1 - 5 * -1 - 3
Multiply
2 - 5 * -1 - 3
Multiply
y = 2 + 5 - 3
y = 7 - 3
y = 4
