Step-by-step explanation:
Given: r = 4 cm
The surface area A of a sphere is given by


Answer:
p = 3.5 or p = 7/2
Step-by-step explanation:
-4p+9= -5
or, -4p = - 14
or, p = -14/-4
or, p = 7/2 = 3.5
1) plug -5 in for the place of x.
2) solve -(-5)^2
3) f(-5)=25
Answer:
Your answer is 31.4 units squared
Step-by-step explanation:
By doing 2πr, you'll get your answer.

Answer:
13.76
Step-by-step explanation:
We want year 10; this means we substitute 10 in place of x:
y=-0.34(10²)+4.43(10)+3.46
y = -0.34(100)+4.43(10)+3.46
y = -34+44.3+3.46 = 13.76
