padilas [110]

Part A:
Given in the statement
r(t)= 2t
A(r) = πr2
So to find A[r(t)]
You have to plug r(t) into A(r)
Answer: A[r(t)] =π(2t)2=4πt

Part B:
The statement tells you t=5 min and
π=3.14

So plug in you values
A[r(t)]=π(2(5))2=4* 3.14*5=62.8

A circle has a radius of square root 98 units and is centered at (5.9, 6.7). Write the equation of this circle. Please help!

weqwewe [10]

Given:

Given that the radius of the circle is √98 units.

The circle is centered at the point (5.9, 6.7)

We need to determine the equation of the circle.

Equation of the circle:

The general form of the equation of the circle is given by

$(x-h)^2+(y-k)^2=r^2$

where (h,k) is the center and r is the radius of the circle.

Substituting the center point (h,k) = (5.9, 6.7) and r = √98, we get;

$(x-5.9)^2+(y-6.7)^2=(\sqrt{98})^2$

Simplifying, we get;

$(x-5.9)^2+(y-6.7)^2=98$

Thus, the equation of the circle is $(x-5.9)^2+(y-6.7)^2=98$

Tcecarenko [31]

Annabelle could arrange her blocks in one row of 42 building blocks as 1 times 42 = 42.

She could also arrange her blocks in 2 rows of 21 blocks because 2 times 21 is also 42.
